Abstract
Bipolar plate, aluminum is one of the most promising alternatives that can capable of uniform distribution of reactive gases over active areas and removal of the heat and exhaust water from the PEMFC. In this work, PEM fuel cell was operated using the bipolar plate constructed of two materials: a channel former made of glassy carbon and a gas isolation plate made of aluminum. Aluminum gas isolation plate at cathode side remained glossy after even1000 h cell operation. In contrast, an oxide layer with a thickness of about 1 μm was formed on the gas isolation plate at anode side. In the simulated corrosion test, a thick oxide layer was formed when aluminum was immersed in water while only a thin oxide layer was formed in the saturated water vapor. The microscopic images, scanning electron microscopy (SEM) images, energy dispersive X-ray (EDX) spectra and transmission electron microscopy (TEM) images were taken to evaluate the surface morphology, elemental composition and other analyses.
