The invention provides a fuel cell system, which has a humidifying apparatus to supply the sufficient moisture to the solid electrolyte membrane of a fuel cell and is capable of preventing the mixture of fuel and oxidant gases in the apparatus. The hydrogen gas supplied to the anode of the fuel cell is humidified in the first humidifier and the air Ad supplied to the cathode is humidified in the second humidifier. The first humidifier has the non-porous water permeable membrane, which is permeable only to the moisture of the cathode off-gas discharged from the cathode of the fuel cell, on the other hand the second humidifier has the porous water permeable membrane, which is permeable to the moisture of the cathode off-gas.

A body (50) of a hydrogen generator of the present invention includes a reformer (10) configured to generate a reformed gas mainly containing hydrogen, a reforming material passage (1) configured to supply a reforming material, which is a material for a reforming reaction, to the reformer, a CO shifter (15) configured to convert CO contained in a reformed gas obtained from the reformer (10) into CO2, a reformed gas passage (2) configured to supply the reformed gas obtained from the reformer (10) to the CO shifter (15), and a passage (3) for the shifted gas obtained from the CO shifter (15). The shifted gas passage (3) and the reforming material passage (1) are adjacent to each other with a shared horizontal wall (31) interposed therebetween, and thereby, heat from the shifted gas and radiant heat from the downstream end face (15b) of the CO shifter are transferred to the reforming material that travels in the reforming material passage (1).
摘要:
A humidifier having a plurality of water-permeable hollow fiber membranes placed along the lengthwise direction of a housing accommodated within the housing in which gases each having a different moisture content flow inside and outside the hollow fiber membranes to carry out moisture exchange whereby the dry air having a low moisture content is humidified is disclosed. The humidifier comprises a bypass channel having a larger diameter than that of the hollow fiber membrane, in which the gas flowing outside the hollow fiber membrane, formed on an approximately central portion of the cross-lengthwise direction of the housing along the lengthwise direction of the housing, and an inlet which introduces the gas flowing outside the hollow fiber membrane into the housing and an outlet which discharges the gas flowing outside the hollow fiber membrane formed on the bypass channel.

The present invention provides the fuel cell system, in which the decrease in the power generation and the degradation of the durability of the fuel cell can be prevented even if the temperature of fuel cell is low at starting or the ambient temperature is low. On the fuel cell starting electric power generation, the air supplied to the cathode inlet is humidified by the hollow fiber membrane humidifier and the hydrogen gas supplied to be anode inlet is humidified by another hollow fiber membrane humidifier. The cooling fluid of the cooling line, which absorbs the heat from the fuel cell and flows into the heat exchanger, heats the hollow fiber membrane humidifiers. Thus the humidification is promoted by heating the humidified air and hydrogen gas to raise their dew-point temperatures.

摘要:
A fuel cell system includes a fuel cell, an oxidant-gas supply passage, a compressor, a water injection device, a return passage, and a regulation valve. The fuel cell is to generate power utilizing an electrochemical reaction between oxidant gas and fuel gas. The oxidant gas flows toward the fuel cell through the oxidant-gas supply passage. The compressor is provided in the oxidant-gas supply passage. The compressor is capable of sucking and pressurizing the oxidant gas to discharge the oxidant gas toward the fuel cell. The water injection device is to inject water toward a suction port of the compressor. The return passage connects an upstream portion in the oxidant-gas supply passage upstream the compressor and a downstream portion in the oxidant-gas supply passage downstream the compressor to bypass the compressor. Opening of the regulation valve is adjustable. The regulation valve is provided in the return passage.
