Abstract

The invention relates to an electrochemical element, especially a fuel cell or a stack of fuel cells, wherein engaging or interlocking, oppositely conical or skewed guiding and fixing means (13,14) are disposed on both sides in or on the frame elements (2) of the membrane-electrode unit (1) and on the biopolar and current collector plates (3,4) for accurately positioned provision, assembly and mutual fixing of adjacent components during mounting. During mounting, the recesses and cavities (13, 14) are automatically guided into each other, initially sliding with a large amount of slip, whereupon they are subsequently positioned in an exact fit and sealed in relation to each other. Mounting is made significantly easier by a seal (10) which is integrated into the frame element (2).
