Title: Hiroaki Fukui: Innovator in Electroconductive Substrates
Introduction
Hiroaki Fukui is a notable inventor based in Shiga, Japan. He has made significant contributions to the field of electroconductive materials, holding 2 patents that showcase his innovative approach to substrate technology.
Latest Patents
Fukui's latest patents include an electroconductive integrated substrate and a process for producing the same. This invention features a porous carbonaceous plate with numerous pores and gas permeability, combined with a gas impermeable electroconductive plate. The two plates are bonded using a thermoplastic resin that is primarily located within the pores of the carbonaceous plate. The resulting integrated substrate exhibits an electrical resistance of not greater than 7 mΩ, with a preferred resistance of not greater than 1.5 mΩ at the bonded surface.
Another significant patent is for a porous electrode substrate for fuel cells. This substrate contains 35 to 60% carbonized resin by weight and features pores with a mean size of 20 to 60 μm. The substrate is designed to have a porosity of 60 to 80% and a compression ratio of 20% or less. The carbon fiber mat used in this invention is created by dispersing chopped carbon fibers in random directions and binding them with an organic binder. The mat is then impregnated with resin and subjected to heat treatment to produce an electrode substrate with excellent characteristics.
