摘要： A liquid fuel mixing apparatus includes a water chamber, a fuel chamber, and a partition arranged substantially vertically between the water chamber and the fuel chamber. The partition includes a passage to permit communication between the water chamber and the fuel chamber. The water chamber includes a first port for the inflow of water and air recovered from a cathode of the fuel cell. The fuel chamber includes a third port for the inflow of unreacted fuel and CO2 from an anode of the fuel cell, a fourth port for the inflow of a liquid fuel from a liquid fuel tank, and a fifth port for the outflow of a mixed fuel to the fuel cell.

摘要： A diaphragm air pump comprises a pump chamber, a diaphragm and one or more piezoelectric beams or bimorphs. Fluid flows into the pump chamber and then flows out of it, the diaphragm is provided within the pump chamber, and one or more central openings are formed in the diaphragm. One or more central check valves are provided in the central openings. The diaphragm is just bonded with piezoelectric beams, not fixed to the lower housing of the pump chamber in order to get large displacement. With the provided diaphragm air pump, it is possible to actively adjust the air quantity according to the requirement for fuel cell or a part-to-be-cooled, and it is also possible to reduce noise and power consumption compared with a conventional fan type cooler or air pumps.
