US 12,506,161 B2 · Method and apparatus for transmitting current and voltage signals of fuel cell based on connector

Abstract

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.
