燃料电池将化学能直接转化为电能，效率高，污染物排放低。然而，在燃料电池技术能够获得电力市场的重要份额之前，必须解决一些重要的问题。这些问题包括燃料的最佳选择，以及燃料电池堆中替代材料的开发。目前的燃料电池原型通常使用25年前选择的材料。商业化方面，包括成本和耐用性，揭示了其中一些材料的不足。在这里，我们总结了在寻找和开发创新的替代材料的最新进展。
Fuel cells convert chemical energy directly into electrical energy with high efficiency and low emission of pollutants. However, before fuel-cell technology can gain a significant share of the electrical power market, important issues have to be addressed. These issues include optimal choice of fuel, and the development of alternative materials in the fuel-cell stack. Present fuel-cell prototypes often use materials selected more than 25 years ago. Commercialization aspects, including cost and durability, have revealed inadequacies in some of these materials. Here we summarize recent progress in the search and development of innovative alternative materials.
