摘要： A composition with latent adhesion, fuel cell stack with a bipolar plate assembly with latent adhesion and a method of assembling a fuel cell stack with a seal that has latent adhesion such that reactant or coolant leakage through the seal is reduced. Bipolar plates within the stack include reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, all of which are formed within a coolant-engaging or reactant-engaging surface of the plate. One or more thin or low aspect-ratio seals are formed on a metal bead that is integrally formed on a surface of the plate and is used to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths that are defined between adjacently placed plates. By proper formulation of the precursor materials that make up the seal, the activation of the adhesive bond formed between the seal and an adjacent surface within the fuel cell can be delayed to allow ample time to aligned and compressively join the cell assemblies in a stack housing. This in turn improves the ability of the seal and its adjacent surface to avoid seal damage and concomitant reactant or coolant leakage.

摘要： The purpose of this invention is to make it easy to handle all-rubber gaskets. To achieve this purpose, a gasket is characterized in that a gasket body of only rubber is combined with a carrier film that is made from a resin film to hold the gasket body in a non-adhesive state. A three-dimensional portion having a shape that is deformed along the external shape of the gasket body is provided at a position where the gasket body and a plane of the carrier film overlap, and a portion of the gasket body is contained in the three-dimensional section. The gasket body is used as a gasket for fuel cells incorporated into a fuel cell stack.

摘要： Hydrofluoroolefin (HFO) fluid can be transported through an electrochemical device, which has a proton exchange membrane (PEM) disposed between a pair of gas-permeable electrodes that include respective catalysts. At an inlet side, the catalyst facilitates reaction of HFO with hydrogen carrier gas. The resulting cation is transported across PEM in the presence of an electric field applied to the electrodes. At an outlet side, the catalyst of the opposing electrode facilitates dissociation of the cation back into HFO and hydrogen. In some embodiments, the transported HFO has a higher pressure than that before the electrochemical device. In some embodiments, the electrochemical device can be operated in reverse to expand HFO fluid and/or to recapture power. The electrochemical device can thus be used as a compressor or expander for vapor-phase HFO or as a pump or expander for liquid-phase HFO, for example, in power generation or heating/cooling cycles.

摘要： First, a passive film is removed from a surface of a separator sheet. For example, the separator sheet may be immersed in an acidic liquid to remove the passive film. Then, the separator sheet is washed with water, taken out from the water, and heated. After the heating, the separator sheet is subjected to an electrolytic treatment to obtain a separator for a fuel cell. The resultant separator has a seal forming portion, and the outermost surface of the seal forming portion contains, based on 100% by weight of the total of a Cr oxide, an Mo oxide, an Fe oxide, Fe, and Ni, 5% by weight or less of the sum of the Fe and Ni and 60% by weight or more of the Cr oxide.

摘要： A fuel cell stack with a bipolar plate assembly and a method of assembling a fuel cell stack such that reactant or coolant leakage is reduced. Bipolar plates within the system include reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, all of which are formed within a coolant-engaging or reactant-engaging surface of the plate. One or more thin or low aspect-ratio microseals are also formed on a metal bead that is integrally-formed on a surface of the plate and is used to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths that are defined between adjacently-placed plates. By delaying the activation of the adhesive bond formed between the microseal and an adjacent surface within the fuel cell until after the aligned cell assemblies have been compressively supported in a stack housing, the ability of the microseal and its adjacent surface to avoid reactant or coolant leakage is enhanced.
