An all‐solid‐state hydrogen fuel composite composed of ammonia borane (AB), a chemical hydride containing 19.6 wt% hydrogen, and mucic acid (MA) is used as a hydrogen fuel source in thermal dehydrogenation. AB thermolysis provides a hydrogen‐driven proton‐exchange membrane fuel cell with selective, on‐demand hydrogen generation by simply heating the pellet‐type composite. MA, a six‐carbon sugar acid containing two carboxylic acid groups at the C1 and C6 positions and four hydroxyl groups at the C2, C3, C4, and C5 positions, forms an optimized composite with AB (AB:MA = 8:2) to undergo a thermal dehydrogenation reaction to produce 10.77 wt% pure H₂ at 80 °C in 1 min. Adipic acid (AA), a six‐carbon dioic acid without hydroxyl groups, is used as an analogue of MA and shows no catalytic effect in the AB+AA thermolysis process. It is believed that the AB+MA composite obeys the conventional alcoholysis mechanism in the thermolysis process.

糖酸辅助全固态氨硼烷氢燃料的热解

由氨硼烷（AB），含19.6 wt％氢的化学氢化物和粘液酸（MA）组成的全固态氢燃料复合物用作热脱氢中的氢燃料源。AB热解通过简单地加热颗粒型复合材料，提供了一种氢驱动的质子交换膜燃料电池，可选择性地按需产生氢气。MA，一种六碳糖酸，在C1和C6位置包含两个羧酸基团，在C2，C3，C4和C5位置包含四个羟基，形成具有AB的优化复合物（AB：MA = 8：2）进行热脱氢反应以产生10.77 wt％的纯H ₂在80°C下1分钟。己二酸（AA）是一种不含羟基的六碳二酸，被用作MA的类似物，并且在AB + AA热解过程中没有催化作用。据信AB + MA复合物在热解过程中遵循常规的醇解机理。
