Abstract: A series-connected fuel cell assembly includes a plurality of electrode plates and a plurality of exchange membranes. Each of the exchange membranes is held between two of the electrode plates. The electrode plates include at least three outer electrode plates, each of which is provided with a connecting surface. The connecting surface of one of the outer electrode plates faces toward the connecting surfaces of two of the other outer electrode plates. At least one of the exchange membranes is located between every two face-to-face connecting surfaces of the outer electrode plates. As a result, the series-connected fuel cell assembly has the advantages of less thickness, high voltage, simple manufacturing process, and low cost.

Abstract: A fuel-cell flow regulator is placed in a fuel cell having two entrances, each of which is formed at one of two sides of the fuel cell. The fuel cell is composed of a plurality of single cells, each of which includes a fuel inlet and a fuel passage in communication with the fuel inlet. The fuel passages jointly define a fuel tunnel in communication with all of the entrances. The flow regulator is located at the fuel tunnel and movable back and forth along the fuel tunnel.
