摘要:
A fuel cell includes an anode current collector provided between an anode and a separator for collecting electrical energy generated in the electrolyte electrode assembly, and supplying a fuel gas to an electrode surface of the anode. The separator has at least one fuel gas inlet hole for supplying the fuel gas to the anode current collector. The anode current collector has at least one fuel gas inlet channel having an opening that faces an opening of the fuel gas inlet hole at an end of the fuel gas inlet hole, for allowing the fuel gas supplied through the fuel gas inlet hole to flow into the anode current collector.

摘要:
A fuel cell stack includes a first separator and a second separator. A reactant air flow channel is formed on one surface of the second separator. A fuel gas flow channel is formed on one surface of the first separator. Further, a coolant air flow channel is formed on the first separator, on the other surface opposite to the fuel gas flow channel. The reactant air flow channel is connected between a reactant air inlet and a reactant air outlet. A coolant air flow channel is connected between a coolant air inlet and a coolant air outlet. The reactant air flow channel and the coolant air flow channel are configured such that the pressure loss of the reactant air between the reactant air inlet and the reactant air outlet and the pressure loss of the coolant air between the coolant air inlet and the coolant air outlet are substantially the same.
摘要:
A fuel-cell system with a fuel battery comprising more than one fuel cell having a purge gas passage connecting the fuel battery to a purge gas cylinder, a discharge passage connecting the fuel battery to the exterior, solenoid valves each installed in the passages, and an electronic control unit that opens the solenoid valves to open the passages to supply the purge gas to the fuel battery such that residue in the fuel battery is purged to the exterior by the purge gas. The control unit opens the valves at a time interval determined from an output of a current sensor to conduct purge at optimum timing for the battery operating state so as to prevent accumulation of residue in the fuel battery, while preventing repetition of unnecessary purges. Alternatively, manual valves are provided to be manually opened by an operator to open a fuel gas supply passage to supply the fuel gas such that residue is purged by the fuel gas through the discharge passage, thereby enabling fuel supply and purge of residue at starting of power generation, without using an external power source.
摘要:
A method for improving the quality of bottom and water in water areas where sludge is deposited on the bottom. In a sample water area, lime, activated sludge and anaerobic sludge, diatomaceous earth or zeolite, and photosynthesis bacteria solution are spread. Before spreading, the photosynthesis bacteria solution is infiltrated into at least either one of the activated sludge and anaerobic sludge, and the diatomaceous earth or zeolite. For the above method, four kinds of the above agents are prepared in a predetermined proportion, and they are separately packed.
