Fuel cell system, fuel feed system for fuel cell and portable electric appliance
First Claim
1. A fuel cell system for generating electric power, comprising:
- a fuel cell of a solid polymer;
a rectangular parallelepiped sealing container for accommodating hydrogen occlusion alloy, for occluding hydrogen to be supplied to said fuel cell, said sealing container having an inner surface, an outer surface, a plurality of sides, and at least two confronting sides having having surfaces with the largest area;
a connection portion provided in a hydrogen passage between said sealing container and said fuel cell for detachably connecting said sealing container and said fuel cell;
a valve mechanism provided in said hydrogen passage for opening and shutting a flow of hydrogen gas; and
a flow control mechanism provided in said hydrogen passage for controlling a flow rate of hydrogen gas, said mechanism chosen from the group consisting of a hydrogen pressure control mechanism and a hydrogen flow rate control mechanism.
