Background

The fuel cell is formed by connecting single batteries in series. The overall quality of the fuel cell is in intimate and inseparable relationship with the individual cells. The power of the fuel cells in the current market varies from 30kW to 250kW, and the number of corresponding cells is tens of pieces, more than hundreds of pieces. If a problem occurs in one cell, the overall performance, service life and even safety of the fuel cell stack can be affected. Therefore, most of fuel cell stacks with larger power in the market are provided with a single-chip voltage acquisition module and a single-voltage inspection module, so that the voltage of the single cell can be monitored in real time. However, the probe of the single-chip voltage acquisition module is required to be installed, and the single-chip battery is required to be provided with protruding metal sheets, and the size and the interval between the sheets are required to be matched. This application is feasible for mature fuel cell products, but has various inapplicabilities for fuel cell stacks that are still under development.
