摘要:
A fuel cell power generation system suitable for powering an electric vehicle and which provides high degree of safety when restarting power generation. The system is small in size, light in weight and low in cost of power generation. Three-way valves are provided in an exhaust-passage extending from a fuel-reforming unit and in pipes connecting the fuel-reforming unit, a CO removal unit and a fuel cell and as a gas exhaust valve on an anode side exhaust passage extending from the fuel cell. Accordingly, upon shut down, after exhausting residual reformed gas, combustion exhaust gas from a combustion unit associated with the fuel reforming unit is passed through the respective units for purging the residual reformed gas.

A separator unit inserted into a fuel cell having an electrolyte layer interposed between a fuel electrode and an oxygen electrode is provided with a plate like separator that separates fuel gas supplied to the fuel electrode from oxidizing gas supplied to the oxygen electrode, and a mesh like collector having an opening that forms one of a passage through which the fuel gas flows and a passage through which the oxidizing gas flows. The collector is provided to at least one side of the separator base in abutment against one of the fuel electrode and the oxygen electrode. The separator base has a coolant passage formed therein, through which a coolant is allowed to flow, and an electrode abutment portion of the collector, which abuts against one of the fuel electrode and the oxygen electrode, has an aperture ratio higher than those of other portions of the collector.

A fuel cell power generating apparatus includes a stack of a plurality of fuel cell units each having a cathode and an anode disposed on opposite sides of an electrolyte membrane. A fuel gas supply system supplies fuel gas to the anode, an air supply system supplies air to the cathode and a water supply system supplies liquid water to the cathode. A control unit ensures that, when the apparatus starts up, the cathode is first supplied with air, followed by supply of the liquid water. In a preferred embodiment, the water supply system intermittently sprays the liquid water onto the cathode when the temperature of the fuel cell stack monitored by a temperature sensor falls below a predetermined temperature.

A hybrid type power source control system controls the output of a fuel cell, with disregard of the operation of the vehicle accelerator pedal, responsive to the detected amount of residual charge of the battery, which amount fluctuates as the vehicle travels. For example, the output of the fuel cell system 3 might be 3 kW when the residual charge is from 70% to 90%, 5 kW when the residual charge is from 70% to 60% and 10 kW when the residual charge is below 60%. Consequently, the fuel cell system 3 can generate power with an efficiency of from 30% to 33% and can charge the battery 1 effectively. Because the output of the fuel cell is fixed for each of the rather broad ranges of residual battery charge, thermal fatigue of the fuel cell is prevented because of little output fluctuation. When the electric motor is continuously operated, the fuel cell continuously charges the battery to maintain a fully charged stated, optionally with some allowance for fluctuation thereof. When a fixed charge time is manually input, the output of the fuel cell is selected to fully charge (90%) the battery during the time selected.

In a hot press molding method for press-molding a heated material and cooling the material while holding the material in a mold, during press molding of the material, shape changes including a portion that curves with respect to a longitudinal direction of the material are molded at longitudinal opposite end portions of the material and resistance to thermal contraction force of the material in the longitudinal direction during cooling is imparted. In one embodiment of the present invention, the shape changes molded on the material during the press molding are minute protrusions provided on surfaces of the longitudinal opposite end portions of the material. The invention makes it possible to suppress thermal contraction of the material during cooling in hot press molding to thereby prevent defects associated therewith.
