Membrane Electrode Assembly (MEA)
With a continuous decrease in Pt loading, mass transport resistances within MEA are severely aggravated, especially that the oxygen transport resistance is becoming an obstacle for commercialization of fuel cells. In this chapter, the proton transport in

Preface
Membrane electrode assembly (MEA) is the core component of proton exchange membrane fuel cell, which is composed of proton exchange membrane, cathode and anode catalytic layers and gas diffusion layers. The cost of MEA accounts for more than 60% of that of the total system, and particularly, the cost of platinum (Pt) catalysts accounts for nearly 70% of MEA cost. It has been well recognized that the high cost caused by high Pt loading in MEA is one of the key issues that hinder the commercialization of fuel cells, and thus the most direct way to reduce the cost of fuel cells is to reduce the amount of Pt in the MEA. However, a continuous decrease in the Pt loadin
