Abstract: The invention concerns an energy production unit, of electric energy in particular, comprising a fuel cell (1) and a heat source (2) thermally coupled to the fuel cell (1) at least to allow the rise in temperature of this fuel cell (1). According to the invention, it is provided that the heat source (2) comprises a radiating burner (20), that the fuel cell (1) is confined within a thermal insulation enclosure itself heated by the combustion gases (F) derived from the burner (20), and that this unit also comprises temperature regulation means (4) capable of controlling, from around 200° C. to at least 800° C., the temperature of the combustion gases (F) heating the enclosure 3.

Abstract: The invention relates to a radiant gas burner device comprising a first cylindrical chamber (1) and a first injector (2) for feeding the first chamber with a combustible gas mixture, the first chamber (1) comprising an external peripheral heating surface (10). The device of the invention further comprises a second cylindrical and hollow second chamber, and a second injector (4) for feeding the second chamber with a combustible gas mixture, the second chamber being positioned inside the first chamber (1), separated from the first chamber by a sealed wall, and having an internal heating surface (30), and the first and second injectors (2, 4) being designed for separately feeding the first and second chambers, independently of each other.
