Description
Technical Field
The utility model belongs to the technical field of fuel cells, and particularly relates to a liquid hydrogen comprehensive utilization system of a fuel cell rail transit vehicle.
Background
Environmental pollution, global warming, resource scarcity and the like, and the development of new energy resources is forced to be enhanced. The hydrogen energy is regarded as important secondary energy in the new century because of the characteristics of high energy-containing property, high energy conversion rate, zero emission of carbon and the like. The low-temperature liquid hydrogen storage mode is receiving more and more attention due to the characteristics of high hydrogen storage density per unit mass, good safety performance and the like.
A fuel cell is a power generation device that converts chemical energy into electrical energy through an electrochemical reaction, typically using hydrogen and oxygen as reactant substances. As an application of a new power generation technology for directly converting chemical energy into electric energy, a fuel cell has many unique advantages: firstly, the heat loss is small, the generating efficiency is high, generally can reach 40% -50%, and can reach 60% -70% at most, and is not influenced by load variation.

Thirdly, the adaptability of the raw fuel is strong, and the fuel used by the fuel cell can be various.
