  "textContent": "A direct oxidation fuel cell including at least one cell, the cell being a stacked body including: a membrane electrode assembly including an anode, a cathode, and an electrolyte membrane disposed between the anode and the cathode; an anode-side separator having a fuel flow channel for supplying a liquid fuel to the anode; and a cathode-side separator having an oxidant flow channel for supplying an oxidant to the cathode, in which the anode-side separator includes a first region including an upstream half of the fuel flow channel and a second region including a downstream half of the fuel flow channel, the anode includes an anode catalyst layer in contact with the electrolyte membrane and an anode diffusion layer in contact with the anode-side separator, the anode catalyst layer includes an anode catalyst and a polymer electrolyte, the anode catalyst layer includes an upstream-side region facing the first region and a downstream-side region facing the second region, and the content of the polymer electrolyte in the anode catalyst layer is higher at the upstream-side region than at the downstream-side region, thus lowering the porosity therein at the upstream-side region and consequently decreasing the fuel crossover at the upstream-side region with respect to the downstream-side region.",
