The invention relates to a method for producing a current collector () for a fuel cell. The method comprises the following steps: mixing a power-type or granulate-type base material () with a binding agent () and with fibres () in order to generate a material mixture (), wherein the fibres () have a lower melting point and/or a lower chemical resistance than the base material (); moulding a moulded body () from the material mixture (); debinding the binding agent () from the moulded body (); removing at least one portion of the fibres () from the moulded body (); and sintering the moulded body (). The invention also relates to a fuel cell having a current collector () that is produced by means of a method according to the invention.
