    摘要： When it is detected that the temperature of the fuel cell stack is at the freezing temperature of water or less (step S1), an operation mode using a freezing temperature starting up operation control map is selected (step S2). Freezing temperature starting up operation of the fuel cell stack is performed according to the freezing temperature starting up operation control map (step S3). Then, when it is detected that the temperature of the fuel cell stack exceeds the freezing temperature (step S4), the operation mode using the freezing temperature starting up operation control map is switched to an operation mode using a normal starting up operation control map (step S5). Thus, normal starting up operation is performed according to the normal starting up control map (step S6).

    摘要： A fuel cell which can self-heat in a short time, in which no reaction gas is necessary for combustion, thereby improving the starting performance at low temperatures. The fuel cell comprises a cell structure in which an anode and a cathode are provided on either side of a solid polymer electrolyte membrane. This cell structure has a power generation plane and at least a part of the generation plane is defined as a local generation area so as to locally generate power. The fuel cell may include a pair of separators between which the cell structure is placed, and a reaction gas passage may be formed between the cell structure and each separator. One of a system for supplying a reaction gas to only a part of the reaction gas passage, and a system for supplying a reaction gas to the entire reaction gas passage is switchably selected.

    摘要： In order to improve detecting accuracy in a gas leak detection for a fuel cell, in a gas leak detection method for a fuel cell having a solid polymer electrolyte membrane sandwiched by an anode and a cathode, an output voltage is measured in an activated over-potential region in a state in which the pressure of fuel gas which is supplied to the anode is maintained higher than the pressure of gas which is supplied to the cathode, and a gas leak is determined to exist when the output voltage is lower than a predetermined pressure value.
