- J081054 Study on the electron transport resistance in gas diffusion layer of polymer electrolyte fuel cell
抄録
The cost of PEFC (Polymer Electrolyte Fuel Cell) vehicle should be reduced to spread widely, and to realize cost reduction, high current density operation under the condition of high temperature and low humidification is required. It is important for reduction of ohmic loss at the severe operating conditions to evaluate properly electron transport phenomena derived electric resistance of cell components such as GDL (Gas Diffusion Layer). This research approached to explain difference in electrical resistances among commercially available GDLs made of fabricated carbon fibers from both macroscopic and microscopic viewpoints, which are bulk density of GDLs and graphitization of carbon fibers and binders measured by Raman spectroscopy. The results of measurements indicated that electrical resistivity significantly correlated with both characteristics.
