Hydrogen Consumption Measurement for Fuel Cell Vehicles

Fuel cell vehicle fuel consumption measurement is considerably different from internal combustion engine vehicle fuel consumption measurement. Conventional Carbon Balance Method and Flow Measurement methods for gas consumption within combustion engines are not suitable for fuel cell vehicles. The small quantities of fuel consumed and the characteristics of hydrogen itself impose a challenge for the hydrogen measurement. This paper addresses fuel consumption measurement for fuel cell vehicles using various methods such as mass flow measurement, pressure/temperature/volume method, weigh method as well as other methods. The advantages and disadvantages of these methods are discussed.
