PURPOSE: A fuel cell battery is provided to reduce a cost in manufacturing a fuel cell battery. CONSTITUTION: In a fuel cell battery (1) having a layered product (2) of flat cells (3, 4) with a PEN (positive electrode) as an electrochemical active plate (3) and an inter-connector (4) alternately disposed, the inter-connector (4) having profiling structured so that two kinds of fluid (11, 12) flow while always making contact with the PEN is formed on one layer, a direction converting region (24) to reverse the flow direction of second fluid (12) is provided, and a cell dimension is determined so that an undesirable value of thermal stress is not exceeded in the PEN when it is actuated. |
