  • Patent number: 11171342
    Abstract: The invention relates to a system able to operate reversibly as an SOFC fuel-cell stack or as an SOEC electrolyser. According to the invention, a bypass line or circuit is provided in order to divert if needs be some of the hot gases issued from the chambers referred to as oxygen chambers (anodic chambers in SOEC mode, cathodic chambers in SOFC-stack mode) as this will cool the heat exchanger provided in the circuit through which the oxygen flows.

  • Patent number: 11108061
    Abstract: A clamping chamber in a reactor or fuel cell architecture having a stack of elementary units is above the clamping fittings. The clamping chamber, in which a gas other than the reactive gases will flow, is substantially at the same pressure as the reactive gases in the stack. The pressure of the gas flowing in the clamping chamber above the stack of elementary units will then balance the pressure created by the reactive gases and the gases produced within the stack.
