Problems solved by technology

The traditional test method is to separate fuel cell stack control, inspection and load regulation. The operator controls the stack fuel input, power output and load size respectively, and judges the current working state of the battery according to the battery inspection data. This test method is inefficient. And the control accuracy is low, so it is necessary to design a fuel cell automatic test system that can overcome this problem

Abstract

The present invention discloses a fuel cell automation test system. The system mainly comprises a fuel cell test main controller, a cell polling subsystem, a fuel cell stack generation subsystem and a remote electronic load. The fuel cell test main controller employs a field bus to receive voltage data of the fuel cell stack generation subsystem sent by the cell polling subsystem, the data collection / analog quantity sending plate card is employed to regulate and monitor the fuel cell stack state of the fuel cell stack generation subsystem and the fuel cell stack parameters, and a general interface bus controller is employed to communicate with the remote electronic load. The fuel cell automation test system employs control, test and analysis of the fuel cell stack to realize the fuel cell stack test and the analysis automation and has an important significance for reducing the fuel cell test workload and improving the test precision.

Description

Technical field [0001] The invention relates to the technical field of fuel cell test automation, in particular to an automated test analysis system and method covering three aspects: fuel cell stack control, cell stack state inspection and cell stack performance analysis. Background technique [0002] Fuel Cell is a bipolar plate power generation device with hydrogen or purified reformed gas as fuel, air or pure oxygen as oxidant, and gas flow channels. It has high efficiency and pollution-free characteristics and can be applied Fields such as portable equipment, stationary fuel cell power generation equipment, and vehicle fuel cells. [0003] The fuel cell system usually consists of the following six parts: (1) the battery pack, whose function is to convert the chemical energy of the fuel into electric energy and send it to the load; (2) the hydrogen and oxygen supply device, whose function is to provide fuel to the battery And oxidant, maintain the battery cathode / anode pressur...
