To provide a fuel battery capable of suppressing leakage of a fluid with a simpler structure.SOLUTION: A fuel battery according to the present embodiment comprises: a polymer electrolyte membrane; a cell having an anode electrode and a cathode electrode, nipping the polymer electrolyte membrane; an anode separator having a fuel channel in contact with the anode electrode; a cathode separator having an oxidant channel in contact with the cathode electrode; a seal material on the anode side for separating the fuel; and a seal material on the cathode side for separating an oxidant. At least one long side wall of the fuel channel and the oxidant channel and a long side end part of the seal material are vertical to a flat surface of at least one of the anode separator, the cathode separator, a cell on the anode electrode side, and a cell on the cathode electrode side, and at least one long side wall of the fuel channel and the oxidant channel are in contact with the long side end part of the seal material to seal the fuel or the oxidant.SELECTED DRAWING: Figure 1 【課題】より簡易な構成で流体の漏洩を抑制可能な燃料電池を提供する。【解決手段】本実施形態に係る燃料電池は、高分子電解質膜と、高分子電解質膜を挟むアノード電極およびカソード電極を有するセルと、アノード電極に接触した燃料流路を有するアノードセパレータと、カソード電極に接触した酸化剤流路を有するカソードセパレータと、燃料を隔離するアノード側のシール材と、酸化剤を隔離するカソード側のシール材と、を備え、燃料流路及び酸化剤流路の少なくとも一方の長辺の壁と、シール材の長辺端部とが、アノードセパレータ、カソードセパレータ、アノード電極側のセル、及びカソード電極側のセルの少なくともいずれかの平面に対して垂直であり、燃料流路及び酸化剤流路の少なくとも一方の長辺の壁とシール材の長辺端部が接触して、燃料もしくは酸化剤をシールする。【選択図】図１
