The object of the invention is a method and apparatus for solid oxide fuel cell or solid oxide electrolyzer stack, in which method and apparatus at least first, second and third flow field plates (1a, 1b, 1c) on a stack are arranged in such a manner that each first face (16, 18) is opposed by a second face (15, 17) of a super positioned flow field plate (1a, 1b, 1c). At least one gas of fuel side gas and oxygen rich side gas is fed through at least one opening of an opening for fuel side gas inlet (8, 12) and an opening for oxygen rich side gas. At least one opening of the fuel side gas inlet opening (8, 12) and the oxygen rich side gas opening (7, 11) is formed on at least one edge (19) of the flow field plates (1a, b, 1c) and superposed in relation to each other in order to form a duct, The sealing means (3 - 6) are arranged to block at least one opening in such a manner that at least one direction of the fuel gas flow directions (15, 18) and the oxygen rich gas flow directions (16, 17) is changed at least in one single repetitious structure compared to at least another single repetitious structure. |
