硼氢化钠（NaBH4）因其高能量密度而成为燃料电池混合动力汽车（FCHEV）的理想燃料。目前，作者已经提出并研制了以硼氢化钠为燃料的制氢系统。但该系统在低温水环境下的产氢速度存在问题。研究了柠檬酸催化剂在低温水中提高硼氢化钠产氢速度的效果。阐明了在水解硼氢化钠时，加入柠檬酸溶液可以提高氢的生成速度。经证实，即使使用添加柠檬酸溶液的快速制氢系统，100W燃料电池（FC）的发电特性也没有太大问题。
Sodium borohydride (NaBH4) is attractive as fuel for fuel cell hybrid electric vehicle (FCHEV) because of its high energy density. The authors have proposed and made a hydrogen generation system which uses sodium borohydride as fuel before now. However, as for this system, there has been a problem in the velocity of hydrogen generation under low-temperature water environment. This paper examined citric acid catalyst for improving velocity of hydrogen generation from sodium borohydride under low-temperature water. This paper clarifies that the generation velocity of hydrogen is improved by adding citric acid solution when hydrolyzing sodium borohydride. It was confirmed that there is not much problem in the power generation characteristics of a 100W fuel cell (FC), even if using rapid hydrogen generation system by adding citric acid solution.
