Zusammenfassung:	PROBLEM TO BE SOLVED: To ensure high performance power generation by reducing a distribution of fuel flow rates in fuel channels and uniformizing fuel supply to a fuel electrode, in a fuel cell supplied with liquid fuel. SOLUTION: The fuel channels 2 in a plate 1 are supplied with fuel from supply holes 7a in a fuel distribution board 7, and supplied with carbon dioxide gas from supply holes 8a in a gas distribution board 8. The fuel supply holes 7a and the carbon dioxide gas supply holes 8a are formed separately in correspondence with the respective fuel channels 2. A fuel flow rate in an inlet side of the fuel channels 2 is unconventionally high to reduce a flow rate distribution against an outlet side. A gas-permeable board 9 selectively permeable to gas is disposed in a downstream side of the fuel channels 2, and a water absorbing base is disposed at a terminal end, so that unreacted fuel is separated into gas and liquid, which are discharged separately.
