Abstract
The invention relates to a single corrugated fuel cell and a cell stack. The single cell comprises an anode plate, a cathode plate, and a membrane electrode assembly; the anode plate is of a corrugated structure and a plurality of anode channels and anode ribs are arranged on the anode plate in parallel; the cathode plate is of a corrugated structure engaged with the anode plate and a plurality of cathode channels and cathode ribs are arranged on the cathode plate in parallel; the membrane electrode assembly is arranged between the anode plate and the cathode plate. The single cell presents a corrugated structure in a width direction of the channel. A plurality of single cells are stacked in sequence to form a fuel cell stack. Compared with the prior art, the invention significantly increases the reaction area per unit volume of the fuel cell through the corrugated structural design, thereby improving the power density of the fuel cell. In addition, the present invention has little change to the existing processing and manufacturing technology, and thus has high production feasibility.
