The invention provides a control system and control method for a fuel cell. The control system comprises a gas transmission main line, a humidification branch, a main path flow controller and a branchpath flow controller, wherein the gas transmission main line is connected with a battery stack; the humidification branch is provided with a backflow pipeline and a humidifier arranged on the backflow pipeline, and two ends of the backflow pipeline are connected with the gas transmission main line; the main path flow controller is arranged on the gas transmission main line and located at the upstream of the humidification branch; and the branch path flow controller is arranged on the humidification branch and located at the upstream of the humidifier. The control system performs flow controlon different media (reaction gas and humidification medium) independently through the main path flow controller and the branch path flow controller, achieves the purpose of relatively independent control for multiple variables, avoids the coupling effect of heat between different gases and improves the control flexibility, thereby increasing the operation stability of the system during the testingprocess, and improving the temperature and humidity response rate and the test accuracy.
Description
technical field [0001] The present invention relates to the technical field of fuel cells, in particular to a fuel cell control system and a control method thereof. Background technique [0002] With the increase of global energy consumption and unscientific use, non-renewable energy sources such as fossil fuels will become increasingly exhausted and have a serious impact on the environment. This urgently requires people to develop new energy sources such as hydrogen energy and solar energy to deal with energy crises and environmental pollution question. Hydrogen energy is rich in sources, can be converted efficiently, and has no emission pollution during use. As a carrier of secondary energy, it has important prospects in the fields of industry and transportation. [0003] A hydrogen fuel cell is an energy conversion device that provides an electrochemical reaction site for hydrogen and oxygen. Unlike chemical energy storage batteries, the storage of reaction media (hydro...
