By the design of continuous curve cell structure, the fuel can be used more efficiently. It is also improved the manufacture and durability for the cell.The invention is producing high reaction area honeycomb structure of the micro tube type SOFC by the present technology and advanced ceramics molded film process techniques. By develop new material of cathode, the power performance of SOFC can be enhenced. For the honeycomb structure SOFC, the thickness of cell can be decreased. Overall the design, the SOFC can inprove the performance with smaller volume.The technique and instrument requirement of gel casting molding is not high. For gel casting molding, it is more reliability and easy to operate. Consider the profit, it is positive help for manufacture.
