摘要： The present invention relates to a small fuel cell and a small fuel cell stack each allowing for improved output. Conventionally, in a direct methanol fuel cell, carbon dioxide gas produced at an anode electrode side is exhausted together with a methanol aqueous solution. From the methanol aqueous solution, the carbon dioxide gas is separated, and then the methanol aqueous solution is reused as fuel. In this case, a liquid-gas separation device needs to be provided additionally, which results in a large fuel cell with an increased weight, disadvantageously. The present invention is made to solve such a problem by providing a fuel cell including a first unit cell having a cathode electrode, an electrolyte membrane, an anode electrode, and an anode collector layer in this order; and one or more spacers arranged on the anode collector layer. The anode collector layer has a fuel flow path for supplying fuel to the anode electrode, and a through hole for exhausting a reaction product generated by reaction in the anode electrode. Each of the spacers has an exhaust flow path for exhausting the reaction product to outside the fuel cell. The through hole and the exhaust flow path communicate with each other.
