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.
Claims10
A method of making one or more Solid Oxide Fuel Cells comprising the subsequent steps of:
- assembling layers of support, anode, electrolyte and cathode to form at least one solid oxide fuel cell,
- sintering the at least one fuel cell,
- shaping the at least one fuel cell to the desired dimensions to obtain a cell with a maximum tolerance of 1%.
A method of making a solid oxide fuel cell stack comprising the subsequent steps of:
- assembling layers of sintered solid oxide fuel cells, interconnect, spacing and sealing material to form a fuel cell stack of at least one stack element,
- shaping the assembled fuel cell stack to the desired dimensions to obtain a stack with a maximum tolerance of 1%.
