Abstract: A bipolar plate assembly for a fuel cell includes a cathode sheet assembly and an anode sheet assembly. The cathode sheet assembly includes a first cathode sheet, a second cathode sheet, and a first divider sheet arranged between the first cathode sheet and the second cathode sheet. The anode sheet assembly includes an anode sheet and a second divider sheet arranged on an anode sheet inner surface. The second cathode sheet is arranged on the second divider sheet such that the anode sheet assembly and the cathode sheet assembly form the bipolar plate. The cathode sheet assembly includes passages through which coolant fluid may flow. The first and second divider sheets prevent the fluid from permeating through the cathode and anode sheets and interacting with the adjacent cathode and anode gas diffusion layers.

Abstract: The present disclosure generally relates to systems and methods for impregnating resin in one or more coolant channels in a bipolar plate before or after assembly of the bipolar plates into a fuel cell stack.

Abstract: The present invention concerns an extract of Punica granatum comprising: i. at least 10% by weight of the total weight of the dry extract, of punicalagins; and ii. at least 10% by weight of the total weight of the dry extract, of ellagic acid; and wherein the weight ratio [ellagic acid/punicalagins] is ranging from 0.5 to 2. The present invention also relates to a method of preparation of the said extract Another object of the present invention is a preparation comprising the said extract and at least one water-miscible organic solvent preferably chosen from lower alcohols containing from 2 to 8 carbon atoms and in particular from 2 to 6 atoms. The present invention also concerns a composition comprising the said extract or preparation; a process for the cosmetic treatment of keratin materials, comprising a step of applying the said composition and cosmetic uses of the said extract.
