Process of forming conductive oxide layers in solid oxide fuel cells

摘要

A solid oxide fuel cell is formed in the green state with a binder and then a combination of microwave and conventional heating is employed to first remove the binder at a lower temperature and then sinter the oxides at a higher temperature to form the fuel cell. This heating technique not only reduces the time and power requirement but also eliminates large temperature gradients within the oxide material and reduces the attendant problems of internal cracking, separation of components, blistering and delamination.
