CO-tolerant Catalysts

  • Chapter
PEM Fuel Cell Electrocatalysts and Catalyst Layers

Abstract

Fuel cell systems offer the promise of economically delivering power with environmental and other benefits. Recently, polymer electrolyte membrane fuel cells (PEMFCs) have passed the demonstration phase and have partly reached the commercialization stage due to impressive research efforts. Nevertheless, there are still some technological challenges to be solved. Among those challenges, (i) choice of fuel (gasoline, methanol, or hydrogen), (ii) efficient fuel processing, with reduction of weight, volume, and carbon monoxide (CO) residuals, and (iii) development of anode electrocatalysts tolerant to CO at levels of 50 ppm (with a noble metal loading of 0.1 mg cm-2 or less) are deemed to be the most significant barriers that PEMFCs must overcome to achieve complete commercialization. The first and second challenges are closely related to the source and purity of hydrogen as the fuel.
