REACTOR (SOEC) FOR ELECTROLYSIS OR CO-ELECTROLYSIS OF WATER OR FUEL CELL (SOFC) OPERATING IN A PRESSURIZED OPERATING MODE AND COMPRISING A CLAMPING SYSTEM SUITABLE FOR SUCH AN OPERATING MODE

摘要

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.
