Title: Koichi Yamaguchi: Innovator in Fuel Reforming Technology
Introduction
Koichi Yamaguchi is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of fuel reforming systems, holding a total of 9 patents. His work focuses on enhancing the efficiency and functionality of fuel cell systems.
Latest Patents
Yamaguchi's latest patents include a sophisticated fuel reforming system designed for fuel cell applications. This system features a reformer that generates hydrogen-containing gas to serve as an electromotive fuel. The combustor within the system is uniquely structured with two combustion parts: a main combustion part and a sub-combustion part. A fuel pre-vaporization part is strategically placed between these combustion sections, along with main and sub-fuel injection valves that supply fuel to each part. During the startup of the fuel cell system, specific amounts of fuel and air are subjected to lean combustion in the sub-combustion part. This process allows the fuel to be pre-vaporized using combustion gas from the sub-combustion part, leading to efficient premixed lean combustion in the main combustion part.
Another notable patent is a fuel reforming system that generates burnt gas by burning fuel and air in a burner during system startup. This innovative approach raises the temperatures of both the reforming reactor and carbon monoxide oxidizer by supplying the burnt gas to these components. The temperature of the burnt gas is increased over time, enhancing the overall efficiency of the startup process.
