Solid oxide electrolyte, fuel cell module, and method

摘要

Flexible ceramic sheets with enhanced strain tolerance for electrochemical applications such as solid oxide fuel cell electrolytes incorporate a surface indentation pattern providing a strain tolerance of not less than 0.5% in any direction in the sheet plane, being made from flexible green ceramic sheet comprising a ceramic powder and a thermoplastic organic binder by heating and reshaping the green sheet to form a multidirectional surface corrugation pattern therein, followed by firing to sinter the ceramic powder to a flexible ceramic sheet having a multi-directional surface corrugation pattern.
