SBIR Phase I: Polymer Alloy Seal

小企业创新研究(SBIR)一期项目将开发一种采用高速近红外辐射焊接的聚合物合金材料和密封工艺，以在质子交换膜和直接甲醇燃料电池的组装中形成防水粘结。拟议工作的一个关键目标是筛选候选聚合物，以配制具有最大密封结合强度和最佳抗化学和机械降解性能的合金密封件。。所提出的密封材料和焊接工艺将为新型高效燃料电池制造技术提供一条途径。拟议的技术将提供在所需位置焊接合金密封件的灵活性，以生产一体化的燃料电池结构；从而减少单独组件和组装步骤的数量，提高质量和降低成本。此外，红外线焊接工艺将有助于高速自动化制造。

The Small Business Innovation Research (SBIR) Phase I project will develop a polymer alloy material and sealing process using high-speed near-infrared radiation welding, to form a waterproof bond in the assembly of proton exchange membrane and direct methanol fuel cells. A key objective of the proposed work is to screen candidate polymers to formulate alloy seals with maximum sealing bonding strength and optimum resistance to chemical and mechanical degradation. . The proposed sealing material and welding process will provide a path for new high efficiency fuel cell manufacturing technology. The proposed technology will provide the flexibility to weld alloy seals at needed locations to produce a unitized fuel cell structure; thereby, reducing the number of individual components and assembly steps, increasing quality and reducing costs. Additionally, the infrared welding process will lend itself to high speed automated manufacturing.
