Description

technical field [0001] The invention belongs to the technical field of fuel cell real-time detection, and in particular relates to a fuel cell real-time detection system and method suitable for a 7.0T / 60mm caliber magnetic resonance imager. Background technique [0002] As an important part of modern new energy sources, proton exchange membrane fuel cells have many advantages such as high energy efficiency and environmental friendliness. The performance level of a proton exchange membrane fuel cell is closely related to the water management of the battery. Too little water or the phenomenon of "water flooding" will greatly affect the performance of the battery. The status monitoring of fuel cells in real-time operation and the visual detection of real-time generated products are of great significance to the performance evaluation and performance improvement of fuel cells. The visual test method is the development direction and the latest technology frontier of the fuel cell...
