    摘要： A direct-type fuel cell having excellent power generating characteristics even under operating conditions utilizing a high concentration fuel at low air flow rates. The anode includes an anode-side diffusion layer that faces the fuel flow channel and an anode-side catalyst layer in contact with the electrolyte membrane.
