粘结的燃料电池组件，方法，体系和生产它的密封剂组合物
摘要：
具有改进的密封防止泄漏的燃料电池，包括置于膜电极组件的周围部分上的密封剂，以便固化的密封剂渗透膜电极组件的气体扩散层。通过液体注塑技术施加该密封剂，在膜电极组件的周围部分处形成固化的密封剂组合物。该密封剂可以在低温下，例如小于或等于130℃下热固化，或者可以在室温下通过施加光化辐射而固化。密封剂可以是单份或两部分式密封剂。该密封剂包括用选自环氧基、烯丙基、乙烯基、(甲基)丙烯酸酯、酰亚胺、酰胺、氨基甲酸酯及其结合中的基团官能化的可聚合材料，例如可聚合的单体、低聚物、遥爪聚合物、官能聚合物及其结合物。待粘结的有用的燃料电池部件包括阴极流场板、阳极流场板、树脂框架、气体扩散层、阳极催化剂层、阴极催化剂层、膜电解质、膜电极组件框架，及其结合物。
摘要（英）：

A fuel cell, having improved sealing against leakage includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral potions of the membrane electrode assembly.The sealant may be thermally cured at low temperatures, for example 130 centigrade or less, or may be cured at room temperature through the application of actinic radiation. The encapsulant includes the use of the sealant selected from epoxy, allyl, vinyl, (meth) acrylate, imide, amide, carbamate and its combination of functional groups of polymeric materials can be For example, polymerizable monomers, oligomers, claw away polymers, functional polymers and their conjugates. Useful to be bonded parts including the fuel cell cathode flow field plate, anode flow field plate, resin frame, gas diffusion layer, anode catalyst layer, cathode catalyst layer, electrolyte membrane, membrane electrode assembly framework and its conjugates.
