一种金属氢化物储氢器吸氢应力变化检测装置
技术领域
本发明属于金属氢化物储氢器检测技术领域，特别是涉及一种金属氢化物储氢器吸氢应力变化的检测装置。
背景技术
储氢合金在一定的温度和压力条件下能够可逆的吸收和释放氢气，并且循环寿命性能优异。利用储氢合金的这一特性可以实现氢的储存和使用。反应方程式如下(式中M代表储氢合金，MHx代表金属氢化物)：
吸收氢气过程：
释放氢气过程：
金属氢化物储氢器就是利用储氢合金在一定的温度和压力条件下可逆的吸收/释放氢气这一特性制成的、专门贮存氢气的装置，目前已在燃料电池、氢能汽车等诸多领域普遍应用。金属氢化物储氢器一般包括储氢合金、承载容器、传热机构和附属设备等几部分组成。储氢过程中，储氢合金吸收氢气，生成金属氢化物，同时释放热量，热量由传热机构自承载容器内传递到储氢装置外，储氢过程持续进行；放氢过程中，金属氢化物分解释放氢气，生成储氢合金，同时吸收热量，热量由传热机构自储氢装置外传递到承载容器内，放氢过程持续进行。
储氢合金吸放氢过程除了产生热效应外(ΔH0)，还伴随着体积的变化ΔV。储氢合金用于储氢时，合金粉末通常会被罐装到一个密闭的容器中，合金粉末开始吸氢时，由于反应速度很快，体积急剧膨胀，在一个受限的空间会产生巨大的应力，从而给储氢器带来安全性问题。因此测定金属氢化物储氢器所采用合金吸氢过程中体积的应力变化，对于设计安全可靠的金属氢化物储氢器是非常关键的参数。目前并没有仪器来检测储氢合金粉末吸氢过程的应力变化。
