Abstract:

A method for forming electrical connections between parts of a fuel cell that includes subjecting a contact paste positioned between the parts to alternating flows of gasses having varying high and low partial pressures of oxygen. This method demonstrates the ability to form conductive interconnections that have sufficient mechanical stability because these pastes can be cured at a temperature less than the temperatures of the surrounding materials thus allowing desired portions to be cured while allowing other portions such as the glass or ceramic portions to maintain their desired mechanical and electrical properties.
