Fuel cell

A fuel cell including a plurality of elementary modules stacked on each other in a stacking direction,

• at least one of the elementary modules of the plurality including:
• an oxidation unit configured to generate electrons by means of the oxidation of a fuel with an oxidant the oxidation unit including an anode and a cathode sandwiching an electrolytic membrane,
• an anode block including a fuel transporter support suitable for transporting an anode feed flow containing the fuel to an anode chamber, and an anode electron collector attached to the fuel transporter support,
• a cathode block including an oxidant transporter support suitable for transporting a cathode feed flow containing the oxidant to a cathode chamber, and a cathode electron collector attached to the oxidant transporter support,
• the at least one elementary module being configured so as to define the anode chamber, respectively, the cathode chamber, between the oxidation unit and the fuel transporter support, respectively, the oxidant transporter support,
• the at least one elementary module being such that, prior to the assembly of the at least one elementary module in the plurality of elementary modules of the fuel cell, the anode block, respectively, the cathode block, and the oxidation unit are attached to each other.
