    摘要: The invention relates to a fuel cell (1) comprising at least the following parts: a proton-conducting membrane (2) serving as an electrolyte; catalyst layers (3), which cover the membrane (2) on both sides; gas permeable electrodes provided in the form an anode (4) and cathode (5), which rest on the outwardly pointing surface of the catalyst layers (3); electrically conductive plates (6), which contact the electrodes in an electrically conductive manner while being located at small distances from one another, and which, together with the electrodes, delimit gas-conducting channels, and; gas connections for supplying hydrogen (H2) on one side and oxygen (O2) on the other. The inventive fuel cell (1) is characterized in that the membrane (2) is a hybrid membrane comprising a matrix into which a channel-forming protein is mixed. The invention also relates to advantageous variants of the membrane (2) in which the matrix, for example, contains a molecular sieve/protein adduct.

    摘要: The invention relates to a fuel cell (1), comprising at least the following components: a proton-conducting polymer membrane (2) as the electrolyte; catalyst layers (3) covering the polymer membrane (2) on both sides; gas-permeable electrodes in the form of an anode (4) and a cathode (5), which lie adjacent to the surface of the catalyst layers (3) that faces outwards; electroconductive plates (6), which come into electroconductive contact with the electrodes in at short distances and which together with the electrodes, delimit channels carrying gas; and gas connections for supplying hydrogen (H2) and for supplying oxygen (O2). The inventive fuel cell (1) is characterised in that the polymer membrane (2) is a mixture based on a polymer blend containing at least one first polymer group A which is based on a halogenated and/or sulphonated polyalkene, and one second polymer group B which is based on a vulcanised rubber with a polar character.

    摘要: The invention relates to a fuel cell (1) comprising at least the following components: a proton-conducting polymer membrane (2) acting as the electrolyte, catalyst layers (3) that cover the polymer membrane (2) on both sides, gas-permeable electrodes in the form of an anode (4) and a cathode (5) which rest on a surface of the catalyst layers (3), whereby said surface is directed towards the outside, electroconductive plates (6) which contact the electrodes in an electroconductive manner and at closely adjacent distances and, together with the electrodes, define gas-conducting channels as well as gas supplies for the supply of hydrogen (H2) on the one hand and oxygen (O2) on the other hand. The inventive fuel cell (1) is characterised in that the polymer membrane (2) is a vulcanised caoutchouc mixture on the basis of a halogenated caoutchouc, especially when bromobutyl caoutchouc is used. The invention also relates to advantageous variants of the polymer membrane (2), e.g. when the caoutchouc mixture contains a molecular sieve/acid adduct.
