Abstract
The contents of platinum in Membrane Electrode Assembly (MEA) is very important to the cost of proton exchange membrane fuel cell. In this paper, the contents of platinum in MEA were determined by graphite furnace atomic absorption spectrometry. The influences of the program for graphite furnace and the optimum conditum of experiment were systematically studied. The method is simple, rapid, accurate and practical. The result indicates that the relative standard deviation of Pt determination is less than 2.67%. The rate of recovery is 97.3%-101.2%.
