Oxygen bleeding

Fig. 14. Cleansing by oxygen bleeding of a platinum anode catalyst in the presence of 5-20 ppm CO in the hydrogen fuel, demonstrated for a platinum anode catalyst of ultra-low loading (0.14 mg Pt/cm ), consisting of a Pt/C//ionomer thin film composite bonded to the membrane [21].

The aim of this chapter was to outline a comprehensive method to numerically simulate the many poisoning phenomena that occur in PEM fuel cells and their mitigation methods. A full mathematical formulation for CO, CO2, and H2S poisoning of the anode of PEM fuel cells was put forward. Further, the mathematical formulation for the mitigahon of CO effects using oxygen bleeding and CO-tolerant catalysts was also discussed. [Pg.280]
