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 controlled bath (3) 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. <IMAGE> |
