Development of New Power Train for Honda FCX Fuel Cell Vehicle

Article of Honda R&D Technical Review Vol.15 No.1

Summary

To respond to increasing environmental concerns and demands for clean energy, Honda has developed an emission-free clean power train employing fuel cells. This power train has been fitted in the FCX fuel cell vehicle, which is being simultaneously marketed in Japan and the US in a world first. The new power train is made up of a combined pure hydrogen fuel cell stack and Ultra capacitor system, and a reluctance torque traction motor. In addition to having a zero level of emissions of CO2 and other pollutants, the new power train has raised the energy efficiency of the FCX to 45%, almost 1.5 times that of an electric-gasoline hybrid vehicle (HEV) of equivalent size. The FCX also has higher fuel economy than an HEV, and superior acceleration from a standstill to a gasoline internal combustion engine vehicle (ICEV).
