Difference of metallic bipolar plates for PEM fuel cells

Metallic bipolar plates for Polymer electrolyte membrane (PEM) fuel cells without coatings were tested in single cell tests. Current–voltage curves, lifetime curves and the contaminationwith metal ions were measured. Additionally the surface of the plates was analyzed by several methods. We made bipolar plate from Stainless steel Titanium Aluminum andGraphite made in small dimensions and their performance in the same conditions we compared. In this paper we build single-cell conditions as well we compare. And we showed metallic bipolar plates depending on the circumstances of each building, cost and power requirements are available
