Abstract

See full text

A roller embossing method for flexible graphite polar plates of fuel cells comprises: (1) adjusting a clearance of an embossing roller pair of a roller press to a target thickness value of a monopolar plate; (2) feeding a flexible graphite slab in front of the embossing roller pair, and entangling the flexible graphite slab by means of opposite rotation of the embossing roller pair; (3) after the slab is entangled, continuing to forward roll the slab for 10-100 mm, and then reversely rolling the slab for 5-90 mm by means of synchronous and opposite rotation of an upper and a lower embossing roller, wherein one time of forward rolling and one time of reverse rolling are referred to as reciprocal rolling; (4) forming a polar plate after several times of reciprocal rolling, and separating the polar plate from the embossing rollers; (5) performing subsequent treatment on the roll-formed flexible graphite polar plate.
