Title:
METHOD OF OPERATING FUEL CELL AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2006/085520
Kind Code:
A1
Abstract:
An oxygen feeder having an oxygen container has a high gas pressure in the container and this not only results in the high cost of gas charging of the oxygen container but poses a problem concerning safety during operation. A hydrogen-occluding alloy container (5) is used in which an alloy occluding hydrogen is housed as a hydrogen source. An oxygen-storing container (4b) is used in which a material (23) adsorbing oxygen thereon is housed as an oxygen source. A hydrogen-heating means (11a) which heats the hydrogen-occluding alloy container (5) and an oxygen-heating means (11b) which heats the oxygen-storing container (4b) are provided. The hydrogen-occluding alloy container (5) is heated with the hydrogen-heating means (11a) to release hydrogen which has been occluded by the hydrogen-occluding alloy. Thereafter, the excess waste heat resulting from the heating is introduced into the oxygen-heating means (11b) to heat the oxygen-storing container (4b). Thus, not only oxygen release from the oxygen-adsorbing material (23) is accelerated but the pressure of the oxygen gas is elevated. The hydrogen and oxygen are fed to a fuel cell (1).
