CONSTRUCTION AND FLOW FIELD TYPE OF BIPOLAR PLATE FOR DIRECT METHANOL FUEL CELL

摘要

A bipolar plate for a direct methanol fuel cell is provided to promote fuel supply, improve dispersibility of fuel supplied, increase a reaction region between fuel and a catalytic layer, and thus improve cell performances of a fuel cell. The bipolar plate(1) for a direct methanol fuel cell includes an inlet(2) and an outlet(3). The structure of the inlet(2) and outlet(3) is configured in such a way that triangled baffles(4) are installed to disperse fluid flow evenly. A flow channel(6) in which fluid develops from the triangled baffles(4) of the inlet(2) and outlet(3) of the bipolar plate(1) to an electrode, has a dispersive type structure. The flow channel(6) of a dispersive type structure consists of taps having any one shape selected from a dot, diamond, square, cone, or inverted triangle.
