Abstract
The water management has a significant effect on power generation performance of the Polymer electrolyte fuel cell (PEFC). Water distribution and temperature distribution give interaction, then the temperature distribution is required for optimizing the water management. Thus to obtain the temperature distribution by the multipoint measurements are important. We have developed the thin film thermocouples by using Micro Electronic Mechanical Systems (MEMS) technology, and the thermocouples are inserted and measured multipoint of local temperature in cells. Finally, we measured temperature difference of 2 degrees between the current collector and the CL.
