ABSTRACT:
A gas diffusing electrode, an electrochemical device, such as fuel cell, employing same and methods of manufacturing same are provided. The gas diffusing electrode at least includes layers made of at least electro-conductive carbon powder or granule and sputtered platinum layers made of platinum laid alternately to form a multilayer structure. The electrochemical device can be down-sized while maintaining a relatively high power generating capacity.
