Abstract
The invention relates to the technical field of angle control systems and methods, in particular to a system and a method for controlling an exhaust valve angle of a methanol fuel cell. The control system comprises a controller, a stepping device, an electric reactor reaction waste gas outlet and an oxygen transmission data acquisition device; the controller controls a displacement of the steppingdevice through data obtained by the oxygen transmission data acquisition device; the stepping device is in contact with the electric reactor reaction waste gas outlet; and the difference of exhaust valve angles affects an oxygen content value E of tail gas emission in the electric reactor reaction waste gas outlet, wherein the oxygen content value E of the tail gas emission is collected through the oxygen transmission data acquisition device. The control method comprises the steps that the oxygen content value E is controlled to be in a range defined in the description. According to the control system provided by the invention, the controller can be used for controlling the stepping device through the data of the oxygen content value E in an oxygen sensor so as to control the valve angleof tail gas of the methanol fuel cell.
Description
technical field [0001] The invention relates to the technical field of an angle control system and a control method thereof, in particular to a control system and a control method for an exhaust valve angle of a methanol fuel cell. Background technique [0002] A fuel cell is a power generation device that converts the chemical energy of fuel directly into electrical energy. The principle of a fuel cell is an electrochemical device whose composition is the same as that of a general battery. Its single cell is composed of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and the electrolyte. The difference is that the active material of the general battery is stored inside the battery, thus limiting the battery capacity. The positive and negative electrodes of the fuel cell itself do not contain active materials, but are just catalytic conversion components. Therefore, the methanol fuel cell ...
