ABSTRACT:
A fuel cell hydrogen recovery system comprises a primary hydrogen absorbing tank adapted for storing hydrogen discharged from a fuel cell and a secondary hydrogen absorbing tank adapted for storing part of hydrogen that is supplied to the fuel cell. The primary hydrogen absorbing tank and the secondary hydrogen absorbing tank are provided so that heat can be exchanged therebetween. Part of hydrogen that is supplied to the fuel cell is supplied to the secondary hydrogen absorbing tank, so that the primary hydrogen absorbing tank is heated by hydrogen absorbing heat generated when hydrogen is absorbed therein, whereby hydrogen absorbed in the primary hydrogen absorbing tank can be re-supplied to the fuel cell.
