WebMay 12, 2024 · Detailed test methods for hydrogen leakage of a static vehicle and hydrogen emission during operation are then established. Finally, the test methods are evaluated using two fuel cell passenger cars. Generally, compared with other studies, there are two main purposes of this work. WebA hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1] Key issues [ edit]
