SURPLUS HYDROGEN PROCESSING METHOD IN REFORM TYPE FUEL CELL POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To surely and efficiently process surplus hydrogen produced at a transition time in a fuel cell electric vehicle provided with a reform type fuel cell system. SOLUTION: An energy storage 16 (charge permitting region) is secured while the load in a fuel cell electric vehicle is stabilized. Surplus power generated by surplus hydrogen produced at a transition time in the fuel cell electric vehicle is charged in the energy storage 16. The surplus power that has not been charged is used for driving accessories such as a compressor 7.
