  "textContent": "A fuel cell capable of providing an SOFC fon-ned so that a thermal cycle resistance is difficult to occur by uniformiz-ing the flow and distribution of air and fuel gas in cells, wherein, when a gas passage hole part having a center through-hole for gas passage provided at the axial center part of a substrate and having a plurality of peripheral through-holes for gas passage disposed symmetrically with respect to the center through-hole is formed, stacked cell substrates can be supported and tightened by the gas passage hole part at the center part, the flows of the fuel gas and oxidizer gas can be optimized, gas distributions can be unifortnized, particularly, temperature distributions can be unifon-nized in radial direction, and a thermal stress due to thermal expansion less oc-curs, and when a gas separate plate is formed by forming a gas passage pattern by etching both surfaces of a metal substrate, the number of stacked component parts can be reduced and the size and weight of the SOFC can be reduced.",
