Proton exchanging film fuel battery test platform

Abstract

The invention provides a testing platform for a proton exchange membrane fuel cell in the fuel cell technical field, comprising an auxiliary system of the fuel cell, a monitoring system and a computer-human interaction part, wherein the auxiliary system of the fuel cell is used to assist a fuel cell set to produce electric power and extract the electric power produced by the fuel cell set; the monitoring system controls the fuel cell set and the auxiliary system of the fuel cell to produce electric power according to the set testing conditions and process requirements of the fuel cell; the computer-human interaction part is used to set the testing conditions and the state of the fuel cell system sent by the monitoring system. The testing platform aims to test the operation status of the fuel cells under different conditions so as to achieve the optimal conditions for the performance and operation of the fuel cells.

Description

technical field [0001] The invention relates to a test platform in the technical field of fuel cells, in particular to a 1-10KW class proton exchange membrane fuel cell test platform for household use. Background technique [0002] Proton exchange membrane fuel cell (PEMFC), with perfluorosulfonic acid solid polymer as electrolyte, Pt / C as catalyst, hydrogen or reformed hydrogen as fuel, air or oxygen as oxidant, converts chemical energy into electrical energy, It is an efficient and clean new energy source. The flow rate, temperature and humidity of hydrogen, the flow rate, temperature and humidity of air, as well as the temperature and other physical parameters of the fuel cell reactor itself have an important impact on the normal operation and efficiency of the fuel cell. Therefore, how to adjust the input of hydrogen and air, control the temperature of the fuel cell stack, and test some physical parameters of the air, hydrogen and fuel cell stack in a wide range accordi...

Problems solved by technology

Its disadvantage lies in its poor flexibility, that is, it can only make the fuel cell stack run, and there are few adjustable parameters; the amount that can be monitored is small. In this paper, only the water temperature and pressure are detected, which cannot fully reflect the operating status of the fuel cell stack and the relationship between various parameters and fuel. The relationship between the performance of the battery stack; the cost is higher, and the PLC is much more expensive than the analog acquisition card used in the present invention
