| ABSTRACT |
|
In response to carbon emission regulations, the automotive industry has turned its attention to hydrogen fuel cell electric vehicles (FCEVs), which use hydrogen as an energy source. This study aims to support the development of hydrogen sensors for FCEVs by measuring the environmental conditions where the sensors are exposed, developing an evaluation rig, and assessing the performance of the sensors. The results from utilizing the hydrogen sensor evaluation rig revealed that under harsh test conditions of 60 °C/75% RH (“C” in (Fig.4) ), all catalytic combustion-type hydrogen sensors exhibited reduced output values. In contrast, under the most extreme condition of 60 °C/100% RH (“D” in (Fig.4) ), the fresh thermal conductivity hydrogen sensor maintained normal output values. These findings will serve as a reference for determining sensor types in future reliability development efforts. |
