Problems solved by technology

Considering the working characteristics of the humidity sensor, its relative humidity measurement range is 0-100%. For the situation where the local relative humidity exceeds 100% to produce liquid water, it is impossible to accurately detect the degree of flooding, and formulate water management strategies
Existing partial water distribution detection imaging technologies, such as neutron imaging technology and X-ray imaging technology, have extremely high requirements on the detection environment and are currently only suitable for laboratory detection
However, the existing visual water distribution detection mostly uses offline analysis, and lacks an intelligent image processing and analysis module to obtain real-time water distribution information

Abstract

The invention discloses a fuel cell water distribution visual on-line detection system which comprises a main controller, a visual fuel cell, a humidity sensor, an image acquisition module, an image processing module, an analysis and diagnosis module, a terminal display device and a terminal database. According to the characteristics of a fuel cell, the image acquisition and processing is carried out on the fuel cell, thus fuel cell liquid water distribution data is extracted, then the fuel cell liquid water distribution data is analyzed and diagnosed through the analysis and diagnosis module, a dynamic water distribution map is established to study the working state of the fuel cell, the water distribution information of the fuel cell is characterized and displayed in real time, key factors which affect the performance and life of the fuel cell are analyzed, and a reasonable fuel cell water management strategy is made.

Description

technical field [0001] The invention belongs to the technical field of image acquisition and processing, and more specifically relates to a visual online detection system for fuel cell water distribution. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) has low operating temperature, fast start-up, high specific power, simple structure, high reliability, and truly "zero emission". It is currently recognized as the first choice for portable power sources, new energy vehicles, and stationary power stations. Generate energy. [0003] The main product of the fuel cell in the working process is water. The current research shows that the content and distribution of water in the electrochemical system of the fuel cell is one of the main factors affecting the output power, stability and life of the PEMFC. On the one hand, the relative humidity distribution of the fuel cell directly affects the activation degree of the battery, which in turn affects the curre...
