一种应用于两轮车的氢燃料电池动力总成

Abstract

本实用新型公开了一种应用于两轮车的氢燃料电池动力总成，包括底壳、顶架、氢燃料电池、储氢器、泄压引导管及输送管，顶架开设有圆形开口，储氢器的底部开设有泄压口，底壳的底部开设有泄压引导出口；氢燃料电池设置于底壳的内部，顶架安装于底壳的顶部，储氢器通过圆形开口穿设于顶架并设置于底壳的内部；氢燃料电池的入氢端与储氢器的低压出氢端通过输送管相连通，泄压引导管的一端连通于储氢器的泄压口，另一端贯穿于泄压引导出口并延伸至底壳的外部。本方案解决了现有氢燃料电池动力总成中，储氢器泄压阀排出的氢气往往释放于外壳体内部，因缺乏定向导出结构，氢气在外壳体形成的封闭或半封闭环境中聚集后浓度过高，易引发安全风险的问题。
