Holding member for holding an electrochemical cell, a holding substrate for the same, an electrochemical system and a connecting member for electrochemical cells

摘要

The invention provides an assembly structure for facilitating assembly of laminated cells, for reducing the possibility of gas leakage and for preventing the reduction of generating efficiency of cells due to gas leakage. In a disclosed embodiment, a plate-shaped electrochemical cell 9 made of a ceramic material with a through hole 9 a formed therein is held by a holding member 1 . The member 1 is made of a ceramic material and has a plate-shaped main body 1 a of a shape of a flat plate and a protruded portion 1 b. A first supply hole 2 A for supplying one gas and a second supply hole 2 B for supplying the other gas are formed in the holding member 1 . The main body 1 a has a sealing surface 1 c against the one main face 9 a of the cell 9 while the protruded portion 1 b is inserted into the through hole 9 a.
