氢的储存和分配将是任何使用氢作为能量载体的可再生能源基础设施的两个非常重要的方面。硼氢化钠（NaBH4）等化合物中氢的化学储存可以在克服目前与这些方面相关的困难方面发挥重要作用。硼氢化钠是一种非常有吸引力的材料，因为它的高氢含量。在本文中，我们描述了一个反应器，其中一个稳定的钴基催化剂支撑在商业堇青石蜂窝状单体（CHM）用于水解碱性稳定的NaBH4（SBH）水溶液。该设备能够在高达5 bar和130°C的条件下工作，提供高达32 L min - 1的产氢率。
Hydrogen storage and distribution will be two very important aspects of any renewable energy infrastructure that uses hydrogen as energy vector. The chemical storage of hydrogen in compounds like sodium borohydride (NaBH4) could play an important role in overcoming current difficulties associated with these aspects. Sodium borohydride is a very attractive material due to its high hydrogen content. In this paper, we describe a reactor where a stable cobalt based catalyst supported on a commercial Cordierite Honeycomb Monolith (CHM) is employed for the hydrolysis of alkaline stabilized NaBH4(SBH) aqueous solutions. The apparatus is able to operate at up to 5 bar and 130 °C, providing a hydrogen generation rate of up to 32 L min−1.
