Beschreibung
Zusammenfassung:	The invention relates to a method for producing a gas diffusion layer (10) for a fuel cell (200), the method having the following steps: - mixing (120): - elongate, electrically and thermally conductive fibres, - electrically and thermally conductive conductivity particles, - a binder for bonding the fibres and the conductivity particles by means of at least one solvent to form at least one gas diffusion layer mixture (100a, 100b), - providing (140) a carrier body (30), - arranging (160) at least one ply (104a, 104b) of the at least one gas diffusion layer mixture (100a, 100b) on an upper face (31) of the carrier body (30), - removing (180) the solvent from the at least one gas diffusion layer mixture (100a, 100b) to produce the gas diffusion layer (10) on the upper face (31) of the carrier body (30).
