当前,以氢气作为燃料的发动机得到了广泛关注。以氢作为燃料的发动机主要有两种形式:氢氧燃料电池以及氢内燃机。氢发动机有诸多优势,例如:排放极低,能源可再生等等。但是氢发动机在发展的道路上还有许多问题,诸如:发动机成本较高,加氢站很少等等。文中主要对当前氢发动机的发展现状,以及对今后氢发动机发展方向展望等问题进行了讨论。 Currently, hydrogen-fueled engines have drawn much attention. There are two major types of engines that use hydrogen as a fuel: oxy-fuel cells and hydrogen internal combustion engines. Hydrogen engines have many advantages, such as: very low emissions, renewable energy and more. However, there are still many problems in the development of hydrogen engines, such as high engine cost, few hydrogen refueling stations and so on. The article mainly discusses the current development status of hydrogen engine and the future development of hydrogen engine and other issues were discussed.
