Abstract

A stacked type fuel cell includes electricity generating modules, at least two cathode flow field plates, and at least one common anode flow field plate. Each electricity generating module includes an anode collector, a cathode collector, a membrane electrode assembly (MEA) between the anode collector and the cathode collector, a fuel diffusion layer, and a cathode moisture layer. The fuel diffusion layer and the cathode moisture layer are respectively located at two sides of the MEA. The anode collector is between the fuel diffusion layer and the MEA, and the cathode collector is between the cathode moisture layer and the MEA. The common anode flow field plate is between two fuel diffusion layers in two adjacent electricity generating modules. The common anode flow field plate and two electricity generating modules located at two sides of the common anode flow field plate are sandwiched between the cathode flow field plates.
