虽然氢通常被认为是一种很有前途的能源载体和化石燃料的替代品，但氢经济的崛起却被一如既往地推迟。这主要是因为制作燃料电池所需的材料成本很高，这些奇妙的系统以电能的形式释放包含在H-2分子中的能量。事实上，燃料电池的两个电极都需要稀有而珍贵的铂作为催化剂。在自然界中，可以找到一种与氢代谢有关的金属酶，称为氢酶。这些天然催化剂可以直接用于生物燃料电池，也可以启发化学家精心设计具有生物灵感的电催化材料。(C)2012年科学院。爱思唯尔·马森公司出版。版权所有。
While hydrogen is often considered as a promising energy vector and an alternative to fossil fuels, the rise of the hydrogen economy is ever and ever postponed. This is mainly due to the high costs of the materials required for the elaboration of fuel cells, these wonderful systems that release the energy contained in the H-2 molecule in the form of electrical power. Indeed, scarce and precious platinum is required as a catalyst at both electrodes of fuel cells. A solution may be found in nature with metalloenzymes involved in hydrogen metabolism, called hydrogenases. These natural catalysts can be used directly in biofuel cells or serve as an inspiration to chemists for the elaboration of bio-inspired electrocatalytic materials. (c) 2012 Academie des sciences.
