| Abstract in different language: | The PEM fuel cell represents currently one of the most common types of fuel cells and the analysis of this fuel cell behavior under various operating conditions is essential for provision of optimum performance. This contribution deals with demonstration of great influence of the oxygen content in oxidant which reacts with fuel (hydrogen) on active surfaces in the centre of fuel cell. Two most common options of oxygen inlet are compared for the clear evidence of significance of the solution of oxygen content issues. The first option represents oxidant such as pure oxygen and the second option represents air with about 21 % of oxygen. The measured data are processed as the polarization and performance curves. The measurement is done with a laboratory set which represent the energy unit which is based on fuel cell with closed construction and the simplest possible design. |
