Abstract
The fuel cell of this invention includes at least one unit cell that includes: a membrane-electrode assembly including an electrolyte membrane sandwiched between an anode and a cathode; an anode-side separator in contact with the anode and having a fuel flow path for supplying a fuel to the anode; and a cathode-side separator in contact with the cathode and having an oxidant flow path for supplying an oxidant to the cathode. The fuel flow path has a first flow channel and a second flow channel, and each of the first flow channel and the second flow channel has a fuel inlet and a fuel outlet. The first flow channel and the second flow channel are adjacent to each other, and the direction of the flow of fuel through the first flow channel is opposite to the direction of the flow of fuel through the second flow channel.
