Title: Toshiaki Murahashi: Innovator in Oxygen Control and Fuel Cell Technology
Introduction
Toshiaki Murahashi is a prominent inventor based in Amagasaki, Japan. He has made significant contributions to the fields of oxygen concentration control and fuel cell technology. With a total of 5 patents to his name, Murahashi continues to push the boundaries of innovation in his field.
Latest Patents
One of his latest inventions is an oxygen concentration or humidity controlling apparatus. This device features an oxygen concentration controlling element where the shortest distance between the anode and cathode, separated by a solid electrolyte film, is set not larger than 50 µm. This design accelerates the back-diffusion of water generated in the cathode to the anode, eliminating the need for a tank or pump to supply water to the anode. Additionally, this apparatus includes a photoelectric element positioned at an opening to the atmospheric air, allowing it to accumulate electric energy in a secondary battery. This innovation results in a space-saving apparatus that can operate continuously even when the power is turned off, functioning both as a humidifier and a dehumidifier.
Another notable patent is for a molten carbonate fuel battery with electrolyte migration control. This battery comprises a stack of molten carbonate fuel cells, featuring a half-cell anode and a half-cell cathode at the positive and negative ends, respectively. The design includes respective separators between the cells, with the half-cell anode containing an anode electrode and an anode reaction gas flow path, while the half-cell cathode includes a cathode electrode and a cathode reaction gas flow path.
