FUEL BATTERY SYSTEM, FUEL BATTERY VEHICLE AND OPERATING METHOD OF FUEL BATTERY SYSTEM

摘要

A fuel battery system (10) is provided with a fuel battery (20) which generates power by being supplied with a reactive gas; an air compressor (C1) for supplying the fuel battery (20) with an oxidizing gas; a pressure sensor (P2) for detecting the pressure of the oxidizing gas; a pressure adjusting valve (C2) for adjusting the pressure of the oxidizing gas; and a controller (50) for adjusting the degree of opening of the pressure adjusting valve (C2) based on the pressure detected by the pressure sensor (P2). When the controller (50) detects an abnormality of the pressure sensor (P2), the pressure adjusting valve (C2) is opened to a prescribed opening degree or more. Thus, when an abnormality is generated in the pressure sensor (P2), the battery can be continuously operated for a while without immediately stopping the battery operation.
