Latest Patents
One of Akifumi Otaka's latest patents is a fuel processor designed for fuel cells. This invention utilizes a temperature detecting sensor to determine the operational state of the fuel processor, whether it is in a warm-up state or a stationary running state. In the warm-up state, the adjusting/supplying unit controls the steam-to-carbon (S/C) ratio of the water/fuel mixed gas to be lower than that in the stationary running state. This adjustment decreases the quantity of water supplied to the vaporizing section, thereby reducing the heat quantity required to create the water/fuel mixed gas. As a result, the time needed to warm the fuel processor is significantly shortened. Additionally, this design prevents excessive water vapor from remaining in the reformed gas, eliminating the risk of condensation within the fuel processor.
Another notable patent is the high-pressure gas supplying system. This system includes a supplying line that transports high-pressure gas from high-pressure tanks. The design features multiple supply piping lines connected to the high-pressure tanks, along with a piping joint section that connects these lines. Check valves are strategically placed in the supply piping lines to ensure a flowing passage when the internal pressure of the high-pressure tank exceeds the pressure at the piping joint section.
