Abstract
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.
