A single working condition multi-sample fuel cell stack testing system and its control method

Abstract

The present invention provides a single working condition multi-sample fuel cell stack testing system and its control method, which can realize synchronous testing of multiple stacks under the same working condition, during one test or in one time period In this way, the data of multiple stacks under test can be obtained, and the test conditions of multiple stacks under test can be guaranteed to be consistent, which can greatly improve the efficiency of test data acquisition, and further reduce the test cost.

Description

technical field [0001] The present invention relates to the field of new energy technology, more specifically, to a single working condition multi-sample fuel cell stack testing system and a control method thereof. Background technique [0002] Proton exchange membrane fuel cell, also known as fuel cell, is considered to be a new energy power generation system that will be developed in the future because of its advantages such as environmental friendliness, high energy conversion rate, no noise and fast response. [0003] A fuel cell uses hydrogen and air as the anode and cathode reaction gases to generate electricity through an electrochemical reaction. [0004] In the fuel cell development project, the electric stack in the fuel cell system is often used as the measured object, and hydrogen and air are supplied to the electric stack through certain equipment and control strategies, and then the operation process of the electric stack is controlled. In this process, it is ...
