Measurement of solidification heat from supercooled water freezing during PEFC cold start and visualization of ice distribution
TL;DR: In this paper, a method of classifying two different freezing modes using 6-μm thickness thin-film thermocouples (TFTCs) was proposed, and the authors conducted in situ measurement of the solidification heat from supercooled water using originally developed TFTCs and further visualized the ice distribution using X-ray CT.

Investigating the vapour transport phenomena inside the cathode gas diffusion layer media by controlling local temperature gradient inside an operating proton exchange membrane fuel cell
TL;DR: In this paper, the effects of temperature gradient inside PEMFC was investigated by controlling it externally with a fine (testing diameter about 30 μ m) and thin (thickness about 6 μ m).

Measurement of temperature difference on catalyst layer surface under rib and channel in PEFC using micro sensors
TL;DR: In this article, the temperature distribution inside the polymer electrolyte fuel cell (PEFC) during power generation is studied. And the results can be used to design the components and flow field and optimize the operating conditions such as gas flow rate and humidification.
