Abstract: The performances of proton exchange membrane fuel cells (PEMFC) can be affected by a variety of parameters，such as operation and geometry parameters，material properties，resulting in an uneven electrochemical performance over the membrane electrode assembly (MEA) active area. In-situ segmented cell measuring techniques can provide the reliable data and speculate the electrochemical reaction mechanism without damaging the structure of fuel cell. This paper reviewed properties of in-situ segmented cell measuring techniques and introduced resistor network，printed circuit board and electromagnetic induction. The features and applications of these techniques were analyzed. Affecting factors，influencing mechanism of various parameters were also investigated.

Key words: fuel cell, in-situ segmented cell measuring technique, operation parameters, current density distribution, performance
