Abstract

The invention relates to an engine, specifically discloses a fuel cell engine, and is used for solving the problem that a fuel cell is utilized as a power source of a rail engine. The fuel cell engine comprises an engine body (1), a driving system and a running system, wherein the running system comprises two two-shaft gear box type steering frames (2); the driving system comprises two permanent magnet synchronization traction motors (3), two traction invertors (4) which can covert the direct current into frequency-adjustable voltage-adjustable three-phase alternating current and a fuel cell (5); the output shaft of each permanent magnet synchronization traction motor (3) is respectively connected with gear boxes of the steering frames (2) through a universal coupling; and the input ends of the traction invertors (4) are connected with the output end of the fuel cell (5). The fuel cell engine provided by the invention has the advantages that the design is reasonable, and the structure is simple.

Description

technical field [0001] The invention relates to a locomotive running on rails, in particular to a fuel cell locomotive. Background technique [0002] Traditional rail locomotives either use diesel engines as power sources, or catenary to provide DC power as power sources. With the rapid development of the economy, energy consumption is increasing day by day, traditional energy resources are decreasing day by day, and energy prices continue to hit historical high prices. At the same time, the rapid economic development has also brought serious environmental problems, seriously affecting the sustainability of the economy. develop. Building a resource-saving and environment-friendly society has become an important national policy of our country. As a new efficient, clean and convenient way of energy utilization - fuel cells, such as Figure 5 As shown, the fuel cell mainly includes a battery stack, such as a battery stack that uses hydrogen and high-pressure air as an electro...
