Abstract
A membrane electrode assembly for a fuel cell provides a current collector adjacent to an electrode catalyst layer. Since electrons passing between the current collector and the electrode catalyst layer do not pass through a diffusion layer or a supporting layer, the diffusion layer or supporting layer may be non-conductive. Thus, various materials that are hydrophilic, hydrophobic, porous, hydrous, or the like can be used for the diffusion layer and the supporting layer, thereby improving the performance of the fuel cell. In addition, manufacturing costs of the membrane electrode assembly can be decreased since the membrane electrode assembly can be manufactured quickly with low energy.
