The world's energy supply has long depended on fossil fuels, but in the search for sustainable solutions, more and more attention is being paid to alternative energy sources, especially clean energy such as hydrogen technologies. In this diploma thesis, we have focused on hydrogen technologies, more specifically on the operation of the proton exchange membrane fuel cell, which was part of an experimental system. Digital data acquisition was performed in the LabVIEW software environment to obtain the polarization curve. We compared this with manually obtained measurements and theoretical values. We found that digital data acquisition offers faster and more accurate results and successfully demonstrated that the digitally acquired polarization curve matches with theoretical assumptions.
