Abstract
In a Proton Exchange Membrane Fuel Cell (PEMFC), the bipolar plates are exposed to oxidant conditions on one side and reducing conditions on the other. The requirement of good electrical and thermal conductivity, good corrosion resistance, low weight, a good impermeability to the reactant gases and low cost restricts the choices of materials to manufacture bipolar plates. The objective of this research is to determine the corrosion resistance of candidate bipolar plate materials in the chemical environment encountered in PEM fuel cells. Several austenitic stainless steels (SS304 and SS316) and nickel alloys have been examined (Inconel 600, Inconel 601, Inconel 625, Incoloy 800H). The out-of-stack tests involved two types of electrochemical measurements, made in solutions that simulate the atmospheres of both the cathode and the anode chambers of a typical fuel cell, bubbled with O2 and H2, respectively, at room temperature and at 50 {degree sign}C.
