Fuel cell stack e.g. polymer electrolyte membrane (PEM) fuel cell stack has gas diffusion layers fixed on adjacent bipolar plate and formed with stabilization layers

摘要

The fuel cell stack comprises several fuel cells (B1-Bn) comprising membrane-electrode assembly and gas diffusion layers (4.1) provided on both sides of membrane-electrode assembly. A bipolar plate (1) is arranged between adjacent fuel cells (B1,B2). The gas diffusion layers are fixed on the adjacent bipolar plate. The gas diffusion layers are formed with the stabilization layers (4.1.1).
