Title:
FUEL BATTERY SYSTEM, ANODE GAS PRODUCTION AMOUNT ESTIMATION APPARATUS, AND METHOD FOR ESTIMATING ANODE GAS PRODUCTION AMOUNT
Document Type and Number:
WIPO Patent Application WO/2007/046545
Kind Code:
A1
Abstract:
This invention provides, for example, a fuel battery system that can sufficiently reduce the concentration of hydrogen in exhaust gas even when a fuel battery is operated in a low power generation efficiency. A bypass valve (B1) is provided between an oxidizing gas supply path (11) and a cathode off-gas flow path (12). When the supply of the oxidizing gas to the cathode is insufficient, pumping hydrogen is contained in the cathode off-gas. Accordingly, in this case, the concentration of hydrogen in the exhaust gas is controlled by regulating the valve opening of the bypass valve (B1) to regulate the flow rate of bypass air.
