IPC: H04L9/00
Filed: 1995-04-26
Abstract: PURPOSE: To provide a miniaturized and power-consumption saving module by supplying no power to a processor subsystem of a security module, while a telephone set is in a standby mode.

Title: Fuel cell system
Inventor: IIO MASATOSHI
IPC: H01M8/04
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a fuel cell system, capable of eliminating poisoning of an electrode catalyst by using a small-sized, practical device. SOLUTION: In normal operation, high-purity hydrogen is separated from part of a reformed gas made by a reformer 2 by using a hydrogen separation film 14 and stored in a tank 15, power generated by a fuel cell is compared with a previously memorized reference value, and, when a drop from the reference value is more than a fixed value, deterioration of an electrode catalyst is judged to have happened, the amount of power generated is reduced, and poisoning eliminating operation is performed by using the high-purity hydrogen only. When degradation of the electrode catalyst of the fuel cell has occurred, the degradation can be eliminated by surely performing the poisoning eliminating operation.  Because the amount of hydrogen separated from the refined gas and stored is far smaller than the whole amount of the reformed gas, a small- sized one is enough for the hydrogen separation film for separating high-purity hydrogen, and therefore this system is practicable in terms of volume and cost.
