    摘要: A method of producing an electrochemical fuel cell device with one or more electrodes containing one or more electrocatalysts. The method involves the steps of, first, affixing a semi-permeable membrane with inhomogeneous conduction pathways to a conducting surface of a first electrode in a predetermined configuration to form a first electrode assembly. This assembly is then immersed in an electrolyte containing at least one electrochemical precursor with for forming an active electrocatalyst on the conducting surface of the first electrode when a potential is applied to the first electrode. The same process can occur with a second electrode assembly which can be joined to the first electrode assembly before or after the electrocatalyst deposition.

    摘要: A method of production of a channel member for fuel cell use comprising a step of obtaining a sheet-shaped first conductor part 11 containing a carbon material of at least one of carbon nanotubes, granular graphite, and carbon fibers and a first resin, a step of laying a sheet-shaped second conductor part 21 containing a carbon material and a second resin with a lower melting point than the first resin to form a sheet-shaped base part 13, a step of transferring a grooved surface 51 to a surface to form a grooved base part 16 provided with groove part 15, a step of laying a sheet-shaped third conductor part 31 containing a carbon material and a third resin with a lower melting point than the first resin, and a step of integrally joining the grooved base part and the third conductor part by hot melt bonding to cover the groove parts.
