Embodiment 2

[0026] A schematic flow chart of Embodiment 2 of a fuel cell power generation system using liquid hydrogen as fuel is shown in figure 2 Shown: This process is applicable to the proton exchange membrane fuel cell system with dynamic drainage technology. Considering the own characteristics of the fuel cell dynamic water drainage technology, combining the fuel cell’s own heat management waterway with the liquid hydrogen system’s heat management waterway, the system will omit the heat exchanger 8 in Embodiment 1, and all water circulation lines are at normal pressure Pipeline, the system is simpler. The specific implementation steps are as follows:

Abstract

The present invention relates to a fuel cell power generation system using liquid hydrogen as fuel, especially a proton exchange membrane fuel cell power generation system, comprising a proton exchange membrane fuel cell module, a liquid hydrogen storage tank, a buffer tank, a water tank, a heat exchanger, and a control valve , radiator, circulating water pump, circulating water pipeline, monitoring unit and control module. The heat of the fuel cell itself is used to provide a heat source for the liquid hydrogen storage tank to realize the gasification of liquid hydrogen, and then to provide gaseous hydrogen for the fuel cell as fuel. Compared with traditional high-pressure gas cylinder hydrogen storage, metal hydrogen storage and other methods, the present invention has the advantages of large hydrogen storage capacity, light weight, small volume, low working pressure, safety and reliability, fast fuel filling speed, simple fuel filling method, etc. Advantages, especially suitable for fuel cell power generation systems with long endurance requirements.

Description

technical field [0001] The invention relates to a fuel cell power generation system using liquid hydrogen as fuel, in particular to a proton exchange membrane fuel cell power generation system using liquid hydrogen as fuel. Background technique [0002] A fuel cell is different from a battery in the traditional sense. It is a high-efficiency power generation device that converts chemical energy stored in fuel and oxidant into electrical energy through electrochemical reactions. Different from the traditional internal combustion engine, although it needs fuel and oxidant like the internal combustion engine, it does not need to be burned, and can complete the chemical reaction at low temperature to realize the power generation function. There are many types of fuel cells, which can be divided into alkaline fuel cells, proton exchange membrane fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells and solid oxide fuel cells according to different electrolytes. Amo...
