Abstract

The invention relates to a fuel cell hydrogen supplying system for a backup power. The fuel cell hydrogen supplying system for the backup power comprises a main hydrogen supplying bottle component and a spare hydrogen bottle component, wherein the main hydrogen supplying bottle component and the spare hydrogen bottle component pass by ball valves, are connected with a differential pressure valve through high-pressure pressure relief valves respectively, and are connected with drain pipes through drain valves respectively; a P1 pressure sensor and a P2 pressure sensor are arranged on the high-pressure pressure relief valves in the main hydrogen supplying bottle component and the spare hydrogen bottle component respectively; the P1 pressure sensor and a P2 pressure sensor are connected with a controller respectively and are used for monitoring pressures of the two hydrogen bottles in real time and converting the pressures into hydrogen margins in real time through the controller; flame arresters for preventing back fire are arranged at the tail ends of the drain pipes; and safety ground interfaces for guiding static electricity generated in the draining process are formed on the drain pipes. The fuel cell hydrogen supplying system for the backup power can not only realize on-line switching to replace the hydrogen bottles, low-voltage safe hydrogen relief and air purge but also estimate the residual pressures of the hydrogen bottles more accurately.

Description

technical field [0001] The invention relates to a hydrogen supply system with online switching and replacement of hydrogen bottles, safe hydrogen pressure relief and pipeline purge functions, and accurate estimation of remaining energy, especially a fuel cell hydrogen supply system used as a backup power supply. Background technique [0002] In today's global energy shortage and high oil prices, it is imperative to find new energy as a substitute for fossil fuels. Fuel cells are considered to be the fourth-generation power generation technology after hydropower, thermal power and atomic power generation. It directly converts the chemical energy of oxidants and reductants into electrical energy through electrocatalytic reactions. It is an efficient, safe, clean and flexible new type of power generation technology. power generation technology. Among them, the proton exchange membrane fuel cell has a wide range of application prospects in ground power stations, electric vehicl...
