一种安全可靠的固态氢化物水解制氢燃料罐,上盖通过螺栓与壳体可拆卸连接,从而可以多次重复使用。由于内胆是烧结多孔结构,因此不会形成封闭承压腔,不承受机械压力,不会因压力过高而变形、破裂,压力由壳体承担,而且在外部压力突然下降时,内胆通过孔隙也可以快速泄压,防止破裂而导致粉尘飘出形成粉尘云,降低粉尘爆炸的风险。类似的,以固态氢化物加热分解产氢的设备同样有类似的突然压力失控的问题,该设计同样适用于此类应用。壳体内部设置台阶来固定石墨纸,避免长时间放置后石墨纸下移。上盖的各个出气口的下侧焊接有多孔结构,以避免燃料罐内里的固态氢化物粉颗粒直接从出气口冲出燃料罐。

The invention relates to the coating of cation exchange membranes with catalytically active substances. The catalytically actively coated cation exchange membranes are used in electrochemical cells, especially in fuel cells (proton exchange membrane fuel cells - PEMFC) or in electrolysers for water electrolysis (polymer electrolyte membrane water electrolysis - PEMWE). In order to counteract the disadvantages of conventional decal processes, an alterative process for coating cation exchange membranes was sought which enables the transfer of electrocatalysts without the need for high temperatures, high pressures and PFAS-based substrates. It was surprisingly found that catalyst layers which are treated, shortly before the transfer step, with a polymer-swelling solvent conducting the cations can be transferred far more easily.
