A reaction cell for a flow battery having flow channels positioned within a recess of a non-porous and non-brittle housing that is also a dielectric. Positioning the flow channels within the recess eliminates the need for end plates, gaskets, and insulators of conventional designs. A current collector and an electrode within the recess have areas approximately equal to the area of the recess such that they fit within the recess and maximize the contact area between them.

The electrochemical cell stack includes an electrochemical cell disposed between a first separator and a second separator. The electrochemical cell includes an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. The solid electrolyte layer, containing a zirconia-based material as a main component, has a downstream part and an upstream part. The downstream part is positioned on a downstream side in a flow direction of a fuel gas in a fuel flow passage between the anode and the first separator.
