<p>A fuel cell and an electrode module constituting this fuel cell. The electrode module (EM) has an electrolyte film (11) containing a proton conductor capable of conducting protons under an unhumidifying condition and supported by a frame (20) of a predetermined shape. The fuel cell (30) comprises the electrode module (EM) and a cooling passage at least on one side of this electrode module (EM). The electrode module (EM) has a frame (20) for supporting the electrolyte film (11), a porous fuel permeable material film (17) carrying a catalyst, and a porous oxygen permeable material film (18) carrying a catalyst layer and hydrophobic substance grains. This fuel cell can be operated in a dry environment over a wide range of operating temperature without humidifying the fuel gas. Scalable cells from small-capacity ones to large- capacity ones can be constituted of the same module.</p> |
