Abstract Silicon micro-hole arrays Si-MHA were fabricated as a gas diffusion layer GDL in a micro fuel cell using the micro-electro-mechanical-systems MEMS fabrication technique. The resistance temperature detector RTD sensor was integrated with the GDL on a bipolar plate to measure the temperature inside the fuel cell. Experimental results demonstrate that temperature was generally linearly related to resistance and that accuracy and sensitivity were within 0.5 °C and 1.68×10-3-°C, respectively. The best experimental performance was 9.37 mW-cm2 at an H2-O2 dry gas flow rate of 30-30 SCCM. Fuel cell temperature during operation was 27 °C, as measured using thermocouples in contact with the backside of the electrode. Fuel cell operating temperature measured in situ was 30.5 °C.
