摘要： A sealing member for a fuel cell of the present invention includes a resin forming a matrix phase, and particles which are formed of rubber-like elastic body and dispersed in the resin. The sealing member exhibits acid resistance due to the resin, as well as elasticity due to the elastic particles, which gives excellent sealing property to the sealing member. Since acid resistance is steadily provided by the resin, unlike the conventional sealing member, the sealing member does not require expensive fluororubber and can be produced at a reduced cost.

摘要： A method of operating a fuel cell assembly and a fuel cell system use a simple construction to restrain deterioration of power generating performance of a fuel cell assembly at a startup in a subfreezing environment. If an ignition switch is turned off is STEP 1, a control unit determines in STEP 3 whether the temperature of a fuel cell assembly (the internal temperature of the fuel cell assembly) is lower than a predetermined temperature, which is higher than the temperature at which the water produced during power generation freezes. If the internal temperature of the fuel cell assembly is the predetermined temperature or higher, then the processing proceeds to STEP 4 wherein a power generating condition is adjusted to cause the internal temperature of the fuel cell assembly to rise. In STEP 5, an alarm device is actuated. The power generation is continued until the internal temperature of the fuel cell assembly reaches the predetermined temperature or higher, and then the power generation is stopped in STEP 8.
