Title:
燃料電池システム
Document Type and Number:
Japanese Patent JP7029630
Kind Code:
B2
Abstract:
A fuel cell system (100) includes: a fuel cell (1) including an anode gas flow channel (1A) and a cathode gas flow channel (1C) and generating electricity from a hydrogen-containing anode gas of the anode gas flow channel and an oxygen-containing cathode gas of the cathode gas flow channel; an anode off-gas emission path (12) through which an anode off-gas emitted from the anode gas flow channel (1A) flows; and a cathode off-gas emission path (13) through which a cathode off-gas emitted from the cathode gas flow channel (1C) flows. After stoppage of generation of electricity by the fuel cell, gas purging is performed in which at least a part of the cathode off-gas emission path (13) is purged with a hydrogen-containing gas having passed through a junction (8) where the anode off-gas emission path and the cathode off-gas emission path meet each other. The hydrogen-containing gas contains at least either the anode gas or the anode off-gas.The purging operation is governed by a controller (20) as a function of the temperature of the fuel cell (1) detected by temperature detector (21).
