摘要： A fuel cell device, wherein, after an output voltage from a main body of a fuel cell is converted using a converter, the relation between the resultant predetermined output voltage V 1 and an output voltage V 2 from a secondary battery is so set as to satisfy V 1>V 2. When, at the time of a sudden change of an external load, the output voltage V from the main body of the fuel cell becomes lower than a predetermined voltage V 3, an output to a charge controlling unit is stopped. When the output voltage V from the main body of the fuel cell is lowered even further and becomes lower than a predetermined voltage V 4, an output to an auxiliary device, which is necessary for driving the fuel cell device, is switched from the output from the converter to the output from the secondary battery.

摘要： An electrode of solid polymer electrolyte fuel cells is produced by a step of preparing a mixed liquid containing an organic solvent, a noble metal catalyst-supporting carbon powder and a colloid of a solid polymer electrolyte having a particle size of from 1 nm to less than 400 nm, the colloid being adsorbed to the carbon powder and a step of forming an electrode by coating the mixed liquid on one side of a gas-diffusible layer. The solid polymer electrolyte is effectively adsorbed to the surface of the catalyst and thus a wide reaction area can be secured. Furthermore, thickness of the solid polymer electrolyte layer can be controlled to one in which hydrogen and oxygen can be easily diffused.
