Title: Hiroshi Matsumori: Innovator in Membrane Electrode Assembly Technology
Introduction
Hiroshi Matsumori is a notable inventor based in Utsunomiya, Japan. He has made significant contributions to the field of membrane electrode assembly technology, holding 2 patents in this area. His work is primarily associated with Honda Motor Co., Ltd., where he continues to innovate and develop advanced technologies.
Latest Patents
Matsumori's latest patents focus on the design and functionality of 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 assembly, a first porous layer is interposed between a first electrode catalyst layer and a first gas diffusion layer in the anode. Similarly, in the cathode, a second porous layer is interposed between a second electrode catalyst layer and a second gas diffusion layer. 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 Matsumori 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 a porous layer interposed between them. This porous layer has a thickness of 5 to 40 µm and a seepage pressure of 10 to 60 kPa, contributing to the overall efficiency of the membrane electrode assembly.
