Title: The Innovative Contributions of Yuichiro Kosaka
Introduction
Yuichiro Kosaka is a prominent inventor based in Utsunomiya, Japan. He has made significant contributions to the field of fuel cell technology, holding a total of eight patents. His work focuses on improving the efficiency and functionality of fuel cells, which are essential for clean energy solutions.
Latest Patents
Among his latest patents is a fuel cell system with purging and a method of operating the same. This invention involves a process where, upon stopping electric power generation of a fuel cell, a hydrogen shutoff valve is closed, and a cathode is purged. Simultaneously, an air introducing valve and the purge valve are opened. The air taken in by the compressor is introduced into the anode through the air introducing tube to exhaust the hydrogen remaining in the anode, replacing it with air. Once the replacement is complete, the compressor is turned off, and the air introducing valve and the purge valve are opened. If the temperature of the fuel cell is determined to be equal to or lower than a threshold, a cathode-prioritized purge and an anode-prioritized purging are performed. Another notable patent is for a fuel cell separator plate and the method for producing it. This separator plate comprises a portion in contact with an electrode and a sealing portion provided around the contact portion, with the contact portion having a larger surface roughness than that of the sealing portion. It is preferably a molded separator plate made of a composite carbon material comprising carbon and a thermosetting resin.
