Beschreibung
Zusammenfassung:	The purpose of the present invention is to obtain a gas diffusion electrode that enables the achievement of a fuel cell which has high drainage performance and maintains good power generation performance, while exhibiting high power generation performance particularly at a low temperature (40°C), if used in the fuel cell. In order to achieve the above-described purpose, the present invention has the following configuration. Namely, a gas diffusion electrode which comprises a microporous layer on at least one surface of a conductive porous substrate, and wherein the microporous layer has a fluorine compound region having a length of 3-10 µm and a void having a length of 3-10 µm.
