A fuel cell with a proton-conducting membrane, on which catalyst material and a collector are arranged on both sides, is characterized by the following features: on the side facing the membrane (14), the collectors (16,18) are provided with an electrically conductive gas-permeable carbon aerogel with a surface roughness of <2 .mu.m; a catalyst layer (15, 17) of platinum or a platinum alloy is in each case applied to the carbon aerogel by material bonding; and a membrane (14), deposited by plasma-chemical means, with a layer thickness of between 3 and 50 .mu.m, is located between the catalyst layers (15, 17).
