Title: Takao Fukumizu: Innovator in Membrane Electrode Assembly Technology
Introduction
Takao Fukumizu is a notable inventor based in Utsunomiya, Japan. He has made significant contributions to the field of membrane electrode assembly technology, holding a total of 4 patents. His work is primarily associated with Honda Motor Co., Ltd., where he has been instrumental in advancing fuel cell technology.
Latest Patents
Fukumizu's latest patents focus on innovative designs for membrane electrode assemblies. One of his patents describes a membrane electrode assembly that is prepared by sandwiching an electrolyte membrane between an anode and a cathode. In this design, a first porous layer is interposed between a first electrode catalyst layer and a first gas diffusion layer in the anode. Similarly, a second porous layer is interposed between a second electrode catalyst layer and a second gas diffusion layer in the cathode. The first piled body of the first gas diffusion layer and the first porous layer has a percolation pressure higher than that of the second piled body, which contains the second gas diffusion layer and the second porous layer. The first piled body has a percolation pressure of 25 to 120 kPa, while the second piled body has a percolation pressure of 5 to 25 kPa.
Another patent by Fukumizu details a membrane electrode assembly that includes a solid polymer electrolyte membrane sandwiched between a pair of electrodes. Each electrode features an electrode catalyst layer and a gas diffusion layer, with the electrode catalyst layer facing the electrolyte membrane. A porous layer, with a thickness of 5 to 40 µm and a seepage pressure of 10 to 60 kPa, is interposed between the electrode catalyst layer and the gas diffusion layer. The porous layers are designed to have a spring constant of 100 to 1000 GPa/m, and the assembly may be devoid of any one of the porous layers.
