GAS DIFFUSION LAYERS WITH INTEGRATED SEALS HAVING INTERLOCKING FEATURES

摘要

A membrane electrode assembly (MEA) is provided for a fuel cell and includes gas diffusion layers with integrated seals having interlocking features. The interlocking features of the gas diffusion layers allow the MEA to be constructed with a catalyst coated membrane between two gas diffusion layers with the integrated seals of the gas diffusion layers interlocking the gas diffusion layers together to complete the MEA.
