This study investigates the development of an in situ micro-temperature sensor, and analyzes the in-plane temperature distribution in a unit polymer electrolyte membrane fuel cell (PEMFC). To measure in-plane temperature distribution accurately, a polyimide-based micro-temperature sensor is...

The operating temperature and internal water accumulation influence the fuel cell performance significantly, and various regions inside the fuel cell still have non-uniformity. At present, only external, invasive, theoretical and simulation methods are available. The real information inside the...
