Abstract

The invention discloses a locomotive traction power system based on a fuel cell. A fuel hydrogen supply module comprises a hydrogen storage device, a pressure relief valve, a first filter, a pressure switch and a first electromagnetic valve, wherein the hydrogen storage device is communicated with a fuel cell hydrogen inlet through a hydrogen supply pipe; the pressure relief valve, the first filter, the pressure switch and the first electromagnetic valve are sequentially arranged on the hydrogen supply pipe; and hydrogen in the hydrogen storage device passes through the pressure relief valve, the first filter, the pressure switch and the first electromagnetic valve respectively and enters an electric pile. The locomotive traction power system based on the fuel cell has the advantages as follows: the total output power of the locomotive traction power system can be changed in real time by regulating air supply flow so as to regulate the rotation speed of a traction motor and control the speed of a locomotive, as a result, integration of a fuel cell and a power system and highly-automatic operation can be achieved; and through application of the hydrogen fuel cell to the locomotive traction power system, the total greenhouse gas emission can be reduced, the pollution to surroundings of a transport route can be reduced, and dependence of railway transport on oil fuel can be reduced.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a locomotive traction power system based on a fuel cell. Background technique [0002] With the continuous deterioration of the environment and the aggravation of the energy crisis, energy researchers are focusing on the research and development of new energy technologies. As a new energy source with no pollution, high efficiency and low noise, fuel cell technology is in line with the trend of future industrial development. A fuel cell is a power generation device that directly converts the chemical energy of externally supplied fuel and oxidant into electrical energy, heat energy, and other reactants through an electrochemical reaction. The current application of fuel cells to locomotive traction power systems has the following problems: the fuel cell integrated system cannot be used to provide power for locomotive traction motors. Contents of the invention [0003] The technical problem to ...
