A hydrogen generation system for fuel-cell (FC) hybrid electric vehicles fueled by powdery sodium tetrahydroborate (STEPS) has been proposed and developed. In this system, it is difficult to control the pressure of the hydrogen supplied to a FC stack. This problem may cause damage to the solid polymer electrolyte membrane of the FC stack or an imbalance in the generated electrical power. As a solution...
A hydrogen generation system for fuel cell hybrid electric vehicles (FCHEVs) which generates large amount of hydrogen rapidly by hydrolysis of powdery sodium tetrahydrob-orate (NaBH4) has been proposed and developed. The system has some problems; one of the problems is difficulty of controlling the supply amount of the hydrogen which is generated by the system to a fuel cell (FC) stack. This problem...
Fuel cell hybrid electric vehicle (FCHEV) is attractive because it has longer driving range than electric vehicle and does not emit greenhouse effect gas. However, there is a problem that the lifetime of fuel cell becomes shorter by degradation progresses under the conditions such as load variation and the operation in considerable lower or higher power than rated power. In order to solve this problem,...
