Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring terminal connectors are used on printed circuit boards to transmit signals, then signal transmission can be achieved, but the number of connectors and signal lines increases dramatically, making the system complex and unreliable
Solution Approach 1:
The patent merges multiple signal transmission functions into a single integrated PCB board with pre-configured signal lines. Instead of using numerous separate spring terminal connectors, the invention integrates current collection arrays, voltage collection arrays, and signal routing into one unified PCB structure that directly interfaces with the fuel cell components, thereby reducing connector quantity and improving reliability
Solution Approach 2:
The PCB board serves multiple functions simultaneously: it collects current signals from multiple regions, collects voltage signals, provides signal amplification, and transmits data to the collection system. This multi-functional integration eliminates the need for separate dedicated connectors for each function, reducing overall system complexity while maintaining comprehensive signal transmission capability
2Reliability
If multiple plug connectors are used to connect signal lines, then signal collection can be achieved, but individual connector problems can affect overall electrical signal collection and greatly affect test reliability
Solution Approach 1:
The invention combines multiple signal collection functions into integrated PCB assemblies that reduce the number of discrete plug connectors. The PCB board integrates current collection, voltage collection, and signal processing into unified structures, minimizing the number of connection points and reducing the probability of connection failures affecting overall test reliability
3Measurement precision
If tens of hundreds of signal lines are formed on the printed circuit board, then complete signal coverage is achieved, but marking and managing each signal line becomes very confusing
Solution Approach 1:
The PCB board is divided into distinct functional regions: current collection arrays, voltage collection arrays, and signal processing areas. Each region is clearly demarcated and assigned specific functions, making it easier to identify and manage signals without requiring individual marking of every signal line. The segmentation provides natural organization that simplifies operation and troubleshooting

AI summary
A printed circuit board transmits the collected current and voltage signals of different regions in a membrane electrode assembly inside the fuel cell to PCB connectors, and transmits the current and voltage signals to a data collection module by means of mating of a male of the connector, a female and a male of the standard harness. The current and voltage signals of the PCB connectors are identified, and a local current density of the fuel cell represented by each signal is positioned according to the position matching relationship, so that the current density distribution in the entire membrane electrode assembly of the fuel cell is finally obtained. According to the scheme, stable and reliable transmission of current and voltage signals of different regions on the membrane electrode assembly inside the fuel cell to the data collection system is realized.
