Exemplary embodiments include a product and a method of a bipolar plate assembly for a fuel cell stack. The bipolar plate assembly includes a first plate with a first border, and a second plate with a second border. A thermoplastic sealant is melted between the first and second borders.

Bipolar plate assembly with thermoplastic sealant and method therefor

A method of forming an electrode of a lithium ion secondary battery includes combining a binder and active particles to form a mixture, coating a surface with the mixture to form a coated article, translating the article along a first plane, cutting a first plurality of carbon fibers, each having a first average length, to form a second plurality of carbon fibers, each having a longitudinal axis and a second average length that is shorter than the first average length, inserting the second plurality of fibers into the mixture layer so that the longitudinal axis of each of at least a portion of the second plurality of fibers is not parallel to the first plane to form a preform, wherein the second plurality of fibers forms a truss structure disposed in three dimensions within the mixture layer, and heating the preform to form the electrode. An electrode is also disclosed.
