这学期我们随后会讨论燃料电池，当我们讲到，关于氧化还原反应和电化学单元时。
And, we'll talk about fuel cells later in the semester when we do the unit on REDOX reactions and electrochemistry.
燃料电池可以当做辅助供电单元使用，比如，当飞机在地面时，可以允许关闭飞机发动机。
The fuel cells could be used as auxiliary power units to produce electricity when an aircraft is on the ground, for example, allowing its engines to be turned off.
本单元主要为厂内锅炉房、脱水装置加热炉、酸气处理装置主燃烧炉、尾气灼烧炉以及放空火炬等燃气设备提供燃料气。
This unit mainly supplies fuel gas for the equipment like in-plant boiler house heater in dehydration unit main combustion furnace in sour gas treatment unit tail gas incinerator and flare stack etc.
