A fuel cell comprising a stack which comprises a plurality of cells, each cell comprising a plurality of fluid flow openings aligned in parallel to form a plurality of fluid flow lines in the stack, two end plates placed at the ends of the stack and at least one traction member connecting the end plates to each other in order to compress the stack, the traction member being mounted in a fluid flow line of the stack.

Fuel cell comprising at least one integrated traction member

The invention relates to a fuel cell comprising a plurality of modules mounted in series with one another so as to form a peripheral structure, each module comprising two end members and a stack of electrochemical cells mounted between two end members, each end member including a mounting face in contact with one of the ends of a stack and an interface face in contact with another interface face of another end member, the mounting face and the interface face being angularly spaced apart by an angle (α) which is between 0.5° and 60°.

Fuel cell with annular structure

An assembly for producing energy may include a fuel cell, a fluidic cell circuit configured to receive a first heat-transfer fluid and arranged at least partially around the fuel cell, a reversible thermodynamic system configured to alternatively: (i) evacuate the thermal energy produced by the fuel cell and transform it into mechanical energy through the first heat-transfer fluid, and (ii) input thermal energy to the fuel cell through the first heat-transfer fluid, wherein the thermodynamic system includes: (a) a fluidic thermodynamic circuit to receive a second heat-transfer fluid; (b) a first exchanger to exchange thermal energy between the fluidic thermodynamic circuit and the fluidic cell circuit; and (c) a second exchanger configured to exchange thermal energy between the fluidic thermodynamic circuit and an external source. The arrangement may improve fuel cell function, particularly for proton exchange membrane, usefully with fuel cell(s), particularly, proton exchange membrane fuel cells, preferably in transport.
