The control method comprises a control method for gas storage and release processes of a primary storage bin, a secondary storage bin and a recovery bin. The gas storage and release processes of the fuel supply system are adjusted by changing kinetic parameters such as temperature, pressure and time of the primary storage bin, the secondary storage bin and the recovery bin to obtain fuel and an oxidant, which are high in gas purity and stable and controllable in gas supply rate; the fuel cell supply system is always kept in the optimal working state; safe operation of the system during the working period is kept; the control efficiency of the fuel cell supply system is improved; the process debugging cycle and the production cost are reduced; and the standard requirements on the supply rate of the fuel cell supply system in the industry are met.

Description

technical field [0001] The invention relates to a method for controlling the gas storage process of a fuel supply system using solid storage materials, belonging to the application field of fuel cell supply systems. Background technique [0002] A fuel cell is an energy conversion device. Unlike conventional batteries, a fuel cell only needs to continuously input fuel and oxidant into the battery, and can continuously convert chemical energy into electrical energy through redox reactions at the anode and cathode. Fuel cells have the characteristics of high energy conversion efficiency, low operating noise, high reliability, simple structure, easy maintenance, no pollution, and zero emission. Equipment using fuel cells as energy suppliers has played an active role in industrial and civil production. On July 9, 2012, the State Council of China issued the "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)" which will Fuel cell vehicles are one of...

Problems solved by technology

[0004] However, the design pattern of the existing fuel cell supply system is not enough to adapt to the application of solid-state storage materials; at the same time, considering the different kinetic conditions of the storage capacity of hydrogen storage and oxygen storage materials and the process of storing / releasing gas (only hydrogen storage materials For example, the kinetic conditions of different hydrogen storage materials such as temperature, pressure and time of storing / releasing gas will affect the final hydrogen utilization effect), so look for hydrogen storage and storage materials that can match each other in terms of time, gas flow and other conditions. Oxygen materials are quite difficult

In addition, the use of hydrogen storage and oxygen storage materials with specific components, and the design of storage bins of specific sizes according to their storage capacity and the kinetic conditions of the storage / release process will limit the development and application of new solid-state storage materials, resulting in manufacturing costs increase and waste of energy
