FUEL BATTERY CELL STRUCTURE
To achieve a fuel battery cell structure capable of suppressing a decrease in sealability and joint strength.SOLUTION: There is provided a fuel battery cell structure (10) having a fuel electrode layer (24), an air electrode layer (28), and an electrolyte layer (26) provided between the fuel electrode layer and the air electrode layer. The fuel battery cell structure includes: a frame-like member (40) provided on the periphery of the electrolyte layer to separate fuel gas circulating in the fuel electrode layer from air circulating in the air electrode layer; a joining member (42) joining the frame-like member and the electrolyte layer to each other and including metal and ceramic; and a seal member (44) provided such that a seal target region (Rs) is air tightly adhered to the electrolyte layer, the seal target region being defined by the inner peripheral part (40a) of the frame-like member and the region (42a) of the joining member in contact with the inner peripheral part.SELECTED DRAWING: Figure 2
【課題】シール性及び接合強度の低下を抑制することのできる燃料電池セル構造を実現する。【解決手段】燃料極層（２４）、空気極層（２８）、及び燃料極層と空気極層の間に設けられた電解質層（２６）を有する燃料電池セル構造（１０）であって、電解質層の周縁部に設けられ、燃料極層に流通する燃料ガスと空気極層に流通する空気とを分離する枠状部材（４０）と、枠状部材と電解質層を相互に接合するとともに、金属及びセラミックスを含む接合部材（４２）と、枠状部材の内周部（４０ａ）と該内周部に接触する接合部材の領域（４２ａ）により画定されるシール対象領域（Ｒｓ）を電解質層に対して気密に密着させるように設けられたシール部材（４４）と、を備える燃料電池セル構造を提供する。【選択図】図２
