Description

Technical Field

[0001] The present application relates to the field of fuel cell technology, and in particular to a fuel cell engine bench durability test method, device and computer equipment. Background Art

[0002] Zero carbon and zero pollution are the future development trends of power. The principle of proton exchange membrane fuel cells is to use the reaction of hydrogen and oxygen to directly convert chemical energy into electrical energy. Due to its advantages such as high energy conversion efficiency and zero pollution, hydrogen fuel cells are one of the best solutions to achieve the above goals.

[0003] A method and device for predicting the life of a fuel cell engine based on measured correlation, the structure and method of which are: obtaining the unit cycle working condition of the fuel cell engine to be predicted; conducting an endurance test; obtaining the average single cell voltage decay rate according to the average single cell voltage of the fuel cell corresponding to the reference current point; calculating the average single cell voltage decay rate under actual vehicle operation, and obtaining the acceleration factor according to the average single cell voltage decay rate and the average single cell voltage decay rate, and obtaining the life prediction mileage range of the fuel cell engine to be predicted. The life prediction of the fuel-electric engine in this patent is for the entire fuel-electric engine industry, and is only based on the assessment of the life of the fuel-electric engine under a specific working condition. Its test working condition is not applicable to the fuel cell engine of a heavy-duty commercial vehicle.

[0004] A method for predicting the life of a fuel cell stack and an engine system and vehicle using the same. A method for predicting the life of a fuel cell stack includes providing a fuel cell engine system, a vehicle prototype and a catalyst material sample, analyzing them, and establishing a data model, entering the analyzed data into the data model to form an original state database; conducting accelerated decay experiments according to different life acceleration conditions or fixed accelerated endurance methods, and completing the design and verification of accelerated verification samples through accelerated decay experiments; extending the operating life of the fuel cell engine system and vehicle prototypes through external intervention, and curing and calibrating the prototypes after the extended life; obtaining samples of the catalyst layer inside the stack for analysis and comparison, and quantitatively evaluating the current life standard. This patent predicts the life of a fuel cell stack using the internal microstructure of the stack, which requires disassembling the stack and requires professional equipment, which is expensive and difficult, and is not practical enough for products.
