Problems solved by technology

[0006] The operation of the stack has the characteristics of using air with low pressure and low flow rate for low power, and using air with high pressure and high flow rate for high power. Therefore, if the test bench with built-in or adjacent air compressor is prepared, if the overall technology is not studied, the air pressure directly used During use, the air compressor is prone to surge at a certain flow rate unique to the air compressor

Abstract

The invention belongs to the field of fuel cell testing, and discloses an energy-saving air supply system of a fuel cell test board, which comprises a main path, the main path comprises an air filter,an air compressor, a cooler, a main path valve, a flow meter and a humidifier which are connected in sequence; the tail end of the humidifier is connected with a cathode inlet of the galvanic pile, and an outlet of the galvanic pile is connected with the back pressure valve; a branch circuit is further arranged in the test board, the branch circuit inlet connecting end is arranged between the cooler and the main circuit valve, and the branch circuit outlet connecting end is arranged between the galvanic pile and the back pressure valve; and a branch regulating valve is arranged on the branch.The system is simple in structure, energy consumption can be remarkably reduced, cost is saved, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fuel cell testing, and the invention relates to an energy-saving gas supply system for a fuel cell test bench, and relates to an energy-saving gas supply system built in or adjacent to the test bench. Specifically, it relates to a battery cathode air supply system of a proton exchange membrane fuel cell test and activation station. Background technique [0002] Research and production of fuel cells requires testing. The equipment used for testing is generally called a test bench. The test bench is composed of several subsystems, including the anode fuel hydrogen supply of the stack, the cooling of the stack, the cathode oxidant air supply of the stack, the electronic load for the consumption of the generated power, and the control system such as the PLC system. Among them, the cathode air supply is the main energy-consuming subsystem, and it is necessary to focus on reducing its energy consumption. [0003] Fuel...
