Abstract
The invention concerns a method for making Solid Oxide Fuel Cells (SOFC) and stacks. The method concerns assembling the layers required for the formation of a fuel cell, sintering the fuel cell and thereafter shaping the cell. When making a fuel cell stack, the sintered fuel cells are assembled with the interconnect, spacing and sealing material to form a stack of at least one stack element, followed by shaping the stack. Shaping is carried out in various ways and maximum tolerances of 1% are obtained.
