A system including an HTE electrolyser, a first steam supply line, a first dihydrogen discharge line, a second dioxygen discharge line, a first heat exchange module configured to ensure a heat exchange between the first steam supply line and the first dihydrogen discharge line, a first module for recovering the thermal energy from the dihydrogen at the outlet of the first heat exchange module in favour of the first supply line, the recovery module comprising a first intermediate exchanger arranged on the first discharge line downstream from the first heat exchange module and configured to transfer the thermal energy from the dihydrogen to an intermediate fluid, and a first intermediate steam generator arranged on the first steam supply line configured to transfer the thermal energy from the intermediate fluid to the liquid water.

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.
