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.

摘要： A miniaturized fuel cell assembly to power portable electronic equipment includes a hydride hydrogen storage unit, a control unit for controlling the flow of hydrogen, a hydrogen supply device interconnecting the hydrogen storage unit and the fuel cell body, and an air feed device to supply oxygen necessary for the generation of electricity.

The miniaturized fuel cell assembly facilitates the effective transfer of waste heat from the fuel cell to the hydrogen storage unit, and as a result of its ability to be used repeatedly, can be utilized for a greater length of time than a conventional primary or secondary power cell.
