description The invention relates to a method for producing a sealed fuel cell (101) for a fuel cell stack (100), comprising a cathode-side distributor plate (K), an anode-side distributor plate (A) and a membrane electrode unit (MEA), said method comprising the following steps: 1) providing a cathode-side distributor plate (K) and an anode-side distributor plate (A), 2) providing a first film web (B1) for sealing the cathode-side distributor plate (K) and a second film web (B2) for sealing the anode-side distributor plate (A), 3) punching a cathode-side distributor structure (VK) for the cathode-side distributor plate (K) out of the first film web (B1) and an anode-side distributor structure (VA) for the anode-side distributor plate (A) out of the second film web (B2), 4) cutting the first film web (B1) to produce a first seal (D1) for the cathode-side distributor structure (VK) and cutting the second film web (B2) to produce a second seal (D2) for the anode-side distributor structure (VA), 5) placing the first seal (D1) on the cathode-side distributor plate (K) and the second seal (D2) on the anode-side distributor plate (A), 6) heating the cathode-side distributor plate (K) and the anode-side distributor plate (A) in order to connect together the first seal (D1) on the cathode-side distributor plate (K) and the second seal (D2) on the anode-side distributor plate (A) in an integrally joined manner, more particularly to melt said seals together.
