新华社报道 由加拿大政府、美国能源部和西门子西屋电气公司合资修建的世界上最大的固体氧化物燃料电池实验热电厂4月7日在多伦多正式动工兴建。有关方面希望通过这项工程来推动环保产业的发展。固体氧化物燃料电池属于清洁能源。用它发电可以直接把化学能转化为电能，使温室效 Xinhua News Agency reported that the world’s largest solid oxide fuel cell experimental thermal power plant, jointly built by the Canadian government, the U.S. Department of Energy, and Siemens Westinghouse Electric, has officially started construction in Toronto on April 7. The relevant parties hope that this project will promote the development of the environmental protection industry. Solid oxide fuel cells are clean energy sources. Using it to generate electricity can directly convert chemical energy into electricity to make the greenhouse effect
