Hydrocarbon based fossil fuels are being used as the main energy resource, burning of which produces carbon dioxide (CO2) and other emissions harmful to environment. Moreover, CO2 is considered as the main contributor to global warming or greenhouse effect. These are the main drivers behind the ongoing research & development in the area of alternative energy sources. Among various alternatives, Hydrogen is identified as the most promising alternative fuel. Hydrogen is the cleanest fuel having some of the most attractive features such as various methods of production from renewable energy (solar, wind, biomass etc.), from fossil fuels etc. H2 as a fuel can be used in various applications such as spark ignition engine, fuel cells etc.Hydrogen has low ignition energy and ensures easy ignition of the ultra-lean mixture with air. The flame speed of hydrogen is about five times higher than methane and gasoline which allows hydrogen fuelled IC engines to have relatively reduced cyclic variations than that of with methane and gasoline. High flame speed also helps to make the combustion closer to constant…

Published 2019-11-21 by SAE International in United States
The three wheeled vehicles are extremely popular in the Indian subcontinent and are constantly posting a positive growth in sales. Given this trend and their polluting nature they can be noted as sizeable contributors to the air quality issues plaguing the metropolitans. With the nation aiming at eradicating the use of internal combustion engines (ICE) in passenger transportation by the year 2030, there have been attempts to convert ICE three-wheelers to battery electric three-wheelers. However, the battery electric three-wheelers, which are quite commonly used for end-mile connectivity, serve to highlight the demerits of the technology pertaining to their range, charge cycles, power to weight ratio, and efficiency. Hydrogen based fuel cells are gaining traction as a potential alternative to batteries due to their efficient and clean power generation. The present paper aims to develop and recommend an optimized power management strategy along with a driveline model for addressing intra-city connectivity in a typical Indian city. The simulation models, considering a parallel hybrid electric three-wheeler with a Proton Exchange Membrane fuel cell as the prime mover,…

Published 2019-11-21 by SAE International in United States
In the view of an eco-friendly environmental future, the major automotive manufacturers are making a move towards electric mobility. The electric vehicle helps to achieve Zero-emission. However, there are some limitations too. The zero-emission Battery electric vehicle (BEV) can provide a limited range only; the market penetration is getting difficult because of an energy storage capability. The addition of an electric vehicle with a fuel cell unit and a hydrogen supply unit can increase the range and the energy capacity of the system. Fuel cell electric vehicle (FCEV) system is faster to refill compared to plug-in Battery electric vehicle (BEV).This study deals with a behavioral analysis of Polymer Electrolyte Membrane (PEM) Fuel cell; with different drive cycles. In this, a fuel cell model developed and simulated in the SIMULINK environment with different drive cycle and results were obtained. The fuel cell controls also were analyzed for the city start/stop cycle.The results obtained from the different drive cycles simulations were analyzed and discussed in this paper. Also, the fuel cell system behavioral analysis experimented on the…

Parameter Identification for One-Dimension Fuel Cell Model Using GA-PSO Algorithm

Tongji University-Mingzhi Shao, Huili Wei, Sichuan Xu
Published 2019-11-04 by SAE International in United States
When studying on how to identify the proton exchange membrane fuel cell model parameters accurately and quickly, the model frequently used is a lumped parameter model. Compared to this kind of model, one-dimensional dynamic proton exchange membrane fuel cell model can correlate the physical parameters with output characteristics of fuel cell to predict the effects of design parameters, materials and environmental conditions, thus reducing the need for experimentation. However, there is little literature about parameter identification for one-dimensional dynamic models currently. In this paper, a one-dimension dynamic proton exchange membrane fuel cell model with many assumptions for reducing the complexity of calculation is realized in Matlab-Simulink environment. The model consists of five interacting subsystems. The GA-PSO hybrid optimization algorithm is used to identify the parameters of fuel cell model to emulate the output characteristics of different proton exchange membrane fuel cells. This hybrid algorithm is an improved Particle Swarm Optimization Algorithm relying on Genetic Algorithm's strong global search ability, with the aim of maintaining the population diversity and avoiding premature convergence. The result shows that…

Study on Air Pressure-Flow Decoupling Control in Fuel Cell System Based on Feedforward Algorithm

Tongji University-Tiancai Ma, Weikang Lin, Yanbo Yang, Zhuoping Yu
Published 2019-11-04 by SAE International in United States
Proton exchange membrane fuel cell (PEMFC) system is considered to be one of the ideal replacement for conventional Internal Combustion Engines (ICE) due to its zero emission, low operating temperature and high power density. The high-pressure PEMFC system has become the future development direction because the higher gas pressure can effectively improve the performance and power density of stack. However, the high gas pressure can lead to the damage of membrane electrode assembly (MEA) and even the failure of fuel cell stack.As the air supply system is a nonlinear system, the flow and pressure have a strong coupling relation. For this problem, firstly, the mathematical model of air supply system is established in MATLAB/Simulink. Then a dual-loop control strategy is used in controller. The static feedforward decoupling algorithm of air pressure-flow and the air pressure closed loop control algorithm are used as external control loops to determine the control objectives of the two actuators: BPV position and air compressor speed. The BPV position closed-loop control algorithm is used as the inner control loop to realize…

Durability Performance of Polymer Electrolyte Membrane Fuel Cells under Open-Circuit Voltage

Tongji University-Xiangyang Zhou, Xiaolang Chen, Bing Li, Cunman Zhang
Published 2019-11-04 by SAE International in United States
Polymer electrolyte membrane fuel cells (PEMFCs) are a good candidate for fuel cell electric vehicles (FCEVs) due to their high efficiency, high power density and zero-emission. However, the lifetime is one of the main barriers to overcome before their commercialization. The durability testing methods for PEMFCs are main include electrocatalyst cycle, catalyst support cycle, membrane electrode assembly (MEA) chemical stability, membrane mechanical cycle and so on. In addition, there is little research about MEA chemical stability test, which applies a continuous open-circuit voltage (OCV) to produce more free radicals and these will have a bad influence on PEMFCs. Based on this, the durability of PEMFC was studied under OCV operation at 30% relative humidity (RH), 90 °C and 150 kPa inlet pressure. The electrochemical performances such as in-situ cyclic voltammetry (CV), linear sweep voltage (LSV) and cell polarization were used to evaluate the durability of PEMFC. Scanning electron microscopy (SEM) was applied to identify the degradation of polymer electrolyte membrane (PEM). After 168 h of durability test, the open circuit voltage decreases from 0.96 to…
