一种无人机燃料电池双极板并联密封与多堆集成封装结构

本发明公开了一种无人机燃料电池双极板并联密封与多堆集成封装结构，包括双极板；若干双极板与膜电极沿垂直方向交替堆叠，相邻双极板之间设有一个膜电极和两个极板并联密封件；双极板上下表面外围开设密封槽，槽底设第一限位沟槽；极板并联密封件由闭环密封垫和贯穿嵌入的若干支撑密封块构成，闭环密封垫一面开设第二限位沟槽，另一面为平面并与膜电极的膜边框贴合形成限位约束；第一、第二限位沟槽对合形成粘接限位密封空腔并填充胶粘限位体；底端盖集成进气口与出气口，配合封装外壳与封顶盖形成一体化绝缘封装。本发明将密封、支撑、定位、限位功能集成一体，有效解决密封垫滑移、蠕变及膜电极错位问题，适配无人机轻量化与极端工况应用需求。
