Architecture and Development of a Hydrogen Sensing and Mitigation System in H2RV - Ford's Concept HEV Propelled With a Hydrogen Engine

Ford's Hydrogen Hybrid Research Vehicle (H²RV) is an industry first parallel hybrid vehicle utilizing a hydrogen internal combustion engine. The goal of this drivable concept vehicle is to marry Ford's extensive hybrid powertrain experience with its hydrogen internal combustion engine technology to produce a low emission, fuel-efficient vehicle. This vehicle is seen as a possible bridge from the petroleum fueled vehicles of today to the fuel cell vehicles envisioned for tomorrow.

A multi-layered hydrogen management strategy was developed for the H²RV. All aspects of the vehicle including the design of the fuel and electrical systems, placement of high-voltage subsystems, and testing, service, and storage procedures were examined to ensure the safe operation of the vehicle. The results of these reviews led to the design of the hydrogen sensing and mitigation system for the H²RV vehicle. This paper focuses on the architecture and development of this system and how it enhances the hydrogen safety of the H²RV vehicle.
