摘要： When stopping an operation of a fuel cell power plant, a controller (30) first stops fuel gas supply to an anode (2), then supplies a dry oxidant gas to a cathode (3) such that the output voltage of the fuel cell stack (1) decreases. The controller (30) then connects a secondary battery (31) to the fuel cell stack (1) so as to consume an output power generated by a reaction of the residual fuel gas in the anode (2). After this processing, the controller (30) replaces the residual fuel gas in the anode (2) with dry oxidant gas, then maintains the fuel cell stack (1) in a closed state, thereby preventing local cell formation in the anode due to mixing of the residual fuel gas with oxidant gas, and hence preventing corrosion of a catalyst layer of the cathode (3) due to local cell corrosion.

摘要： A fuel cell conditioning system and related method are disclosed to condition a fuel cell stack 2 to be ready for use. The fuel cell stack 2 is associated with a cell temperature control device 3, 15 such that a temperature of the fuel cell stack 2 is raised to a normal operating temperature upon which humidified fuel and oxidizer gas are supplied for a given time interval to the fuel cell 2 to generate electric power for that time period. After stopping the generation of electric power, supplying dry air and fuel to the fuel cell stack 2 causes residual moisture to be purged from the fuel cell stack 2. After purging, a temperature of the fuel cell stack 2 is lowered to a value below a freezing point to cause moisture to condense in a solid polymer membrane to contain water. Further, temperature-rise, electric power generation, dry purging and temperature-drop are repeatedly executed.
