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.

Energy production assembly coupling a fuel cell and a reversible thermodynamic system

A roller shutter for an opening leaf of a building, includes a retractable shut-off panel that moves between retracted and deployed positions, and a guide to selectively guide the panel a path between the retracted position and a deployed position in a first plane, and another path is a path between the retracted position and a deployed position in a second plane parallel to said first plane. The guide selectively switches movement of between said first path and said second path. A deployment-switching stop guides the shut-off panel along the second path when the shut-off panel is in contact with the deployment switching stop and the shaft is driven in a direction of rotation for deployment.
