Title: Tatsuji Hatayama: Innovator in Fuel Cell Technology
Introduction
Tatsuji Hatayama is a prominent inventor based in Osaka-fu, Japan. He has made significant contributions to the field of fuel cell technology, holding a total of 3 patents. His innovative work focuses on improving the efficiency and functionality of fuel cell power generation systems.
Latest Patents
One of Hatayama's latest patents is a fuel cell power generating system. This system is designed to supply the air pole of a fuel cell with clean air, free from impurities. It achieves this by incorporating humidification filters that are kept in a wet state through a water supply mechanism. This design enhances the cell's output properties by preventing the decrease of gas dissipation ability and the electric conductance of the solid polymer film caused by impurities.
Another notable patent is for a solid high polymer type fuel cell power generating device. This proton-exchange membrane fuel-cell power generating equipment includes a heat exchanger connected to a process burner and a fan. The system is capable of heating water during startup by circulating it through the heat exchanger while the burner is ignited. Conversely, when cooling is required, the water is circulated through the heat exchanger with the fan operating, but the burner remains off. This innovative design also prevents freezing in the water system when it is not in operation.
