3 Terms and definitions
The terms and definitions defined in GB/T 24548 and the following apply to this document:
3:1
Average cell voltage averagecelvoltage
The ratio of the voltage of a fuel cell stack to the number of cells in the fuel cell stack:
Note: If there are single cells in the fuel cell stack that do not output electrical energy, they are not included in the number of single cells:
3:3
The fuel cell stack current corresponding to the selected power point when the fuel cell engine is subjected to a steady-state characteristic test before the durability test:
Note: PE is the rated power (initial value) of the fuel cell engine: This document selects the fuel cell engine at 100% PE, 50% PE and 10% PE corresponding to the rated power (initial value):
The fuel cell stack currents I100, I50, and I10 are used as reference currents:
3:3
In the durability test, the initial polarization curve test of the fuel cell stack corresponds to an average single cell voltage of 0:700V±0:005V:
Electric current:
3:4
A device for circulating the fluid medium at the anode outlet of the fuel cell stack to the anode inlet of the fuel cell stack:
Note: It is generally composed of a single or multiple combination of hydrogen circulation pumps and ejectors:
