Abstract: An assembly comprising a proton-exchange membrane fuel cell (1) comprising an anode inlet (Ea), a cathode inlet (Ec), an anode outlet (Sa) and a cathode outlet (Sc), said outlets (Sa, Sc) being configured to remove acid-containing exhaust gases (Ga, Gc), the assembly comprising at least one acid-capture device (2) mounted at least at one of the outlets (Sa, Sc) in order to extract at least some of the acid present in the exhaust gases (Ga, Gc) and discharge de-acidified exhaust gases (Ga*, Gc*).

Abstract: The invention relates to a fuel cell (1) comprising a stack (2) comprising a plurality of cells and a plurality of fluid flow shafts, two end plates (3) and a plurality of traction members, at least one end plate (3) has a main device (5) having at least one access opening (51) aligned with a flow shaft and at least one main traction member (T1) configured to apply a main compression to a main body so as to urge the main body (50) against the stack (2) at the flow shaft, and an auxiliary device (6) configured to urge an auxiliary body against the stack (2), the auxiliary compression being applied at a distance from the flow shaft of the stack (2), the main device (5) being mounted removably with respect to the auxiliary device (6).

Abstract: An isolation device configured to be mounted in a fluid flow channel of a fuel cell comprising a stack including a plurality of cells aligned along a stack axis and a plurality of fluid flow channels in the stack. The isolation device comprising a peripheral belt configured to block the fluid communication between the flow channel and at least one flow opening of a cell to be isolated in the stack, the belt being deformable between a first configuration, referred to as an idle configuration, and a second configuration, referred to as a constricted configuration, the cross-section of which is smaller than in the first configuration.
