Title: Hirokazu Ohara: Fuel Cell System Inspection Invention.
Introduction
Hirokazu Ohara is an inventor based in Tokyo, Japan, associated with Honda Motor Co., Ltd. His patent work includes an invention for inspecting a fuel cell system and detecting whether a switching valve has become stuck.
Latest Patents
Ohara is named on 1 patent: “Method of Inspecting a Fuel Cell System, and the Fuel Cell System.” The invention describes an adhesion detection apparatus that checks whether a second switching valve for a sub tank is stuck. It first opens both switching valves while the fuel cell generates power, then closes the first valve while leaving the second open. The apparatus detects possible adhesion by monitoring changes in the pressure sensor’s reading during the second-valve-open state.
Career Highlights
Ohara’s documented patent contribution concerns fuel cell system inspection and valve fault detection. This approach uses pressure measurements during defined operating states to identify a potential switching-valve problem.
Collaborations
The patent lists Masaki Hosoi and Yuji Matsumoto as Ohara’s coworkers. The invention is associated with Honda Motor Co., Ltd.
Conclusion
Hirokazu Ohara’s patent describes a pressure-based method for detecting valve adhesion in a fuel cell system, reflecting a focused contribution to fuel cell inspection technology.
