Abstract
The invention belongs to the field of a battery system, in particular relates to a negative pressure humidification on-board fuel battery system with a perforated plate humidifier. The fuel battery system comprises an air compressor, a humidifier and a fuel battery galvanic pile. The fuel battery system is characterized in that the humidifier is the perforated plate humidifier, the air outlet of the perforated plate humidifier is connected with the air inlet of the air compressor, the air outlet of the air compressor is connected with the air inlet of the fuel battery galvanic pile, and the end gas outlet of the fuel battery galvanic pile is connected with the end gas inlet of the perforated plate humidifier. Compared with the prior art, the perforated plate humidifier provided by the invention effectively improves the humidification efficiency of the perforated plate humidifier, lowers the cost of the humidifier, reduces the volume of the humidifier, namely, reduces the volume of thehumidifier of the fuel battery with 50 kW from 10L to 2L, promotes the stability of the humidifier and prolongs the service life of the humidifier. In addition, as the fuel battery system with the perforated plate humidifier improves the humidification efficiency and stability of the humidifier, the stability of the operation of the fuel battery is also promoted.
Description
technical field [0001] The invention belongs to the field of battery systems, and in particular relates to a negative pressure humidification vehicle-mounted fuel cell system with a porous plate humidifier. Background technique [0002] Energy shortage and environmental pollution are two major technical problems that restrict and affect the development of the traditional automobile industry. With its high efficiency and zero pollution, fuel cells provide a way to solve the world's energy crisis and environmental protection issues. In recent years, the world's major automobile companies and research on fuel cell vehicles have progressed rapidly, and fuel cell vehicles have entered the trial stage. [0003] A fuel cell is a power generation device that directly converts the chemical energy of fuel (hydrogen) into electrical energy through an electrochemical reaction without combustion. The internal core component of the device is the membrane electrode (MEA for short). The m...
