Abstract

The invention relates to a method for producing a current collector (1) for a fuel cell. The method comprises the following steps: mixing a power-type or granulate-type base material (2) with a binding agent (3) and with fibres (4) in order to generate a material mixture (5), wherein the fibres (4) have a lower melting point and/or a lower chemical resistance than the base material (2); moulding a moulded body (6) from the material mixture (5); debinding the binding agent (3) from the moulded body (6); removing at least one portion of the fibres (4) from the moulded body (6); and sintering the moulded body (6). The invention also relates to a fuel cell having a current collector (1) that is produced by means of a method according to the invention.
