The present invention provides a membrane electrode assembly of a fuel cell, comprising a gas diffusion layer, a microporous layer, a catalytic layer, and an electrolyte membrane that are sequentially stacked. In the direction of an air flow path, the thickness of the microporous layer decreases progressively, the thickness of the catalytic layer increases progressively, and the total thickness of the microporous layer and the catalytic layer keeps consistent. The present application also provides a preparation method for the membrane electrode assembly of a fuel cell. The membrane electrode assembly of a fuel cell provided in the present application can balance water content of a gas inlet area and a gas outlet area of the fuel cell, and finally improves the stability of the fuel cell at different temperatures and humidity levels, thereby implementing functions such as improving the durability and decreasing a catalyst load.
