Chemical energy sources transformations by remote experiment

Abstract

The paper describes the first experience with the set up, functioning and data evaluation of the remote experiment "Energy transformation" accessible via Internet (http://remotelab10.truni.sk ) as a part of the e-laboratory at the Department of Physics, Faculty of Education, Trnava University in Trnava, Slovakia. The remote experiment control and data acquisition is based on the system ISES (Internet School Experimental System) and its control program and www page are built using the environment Easy Remote ISES. The main goal of the experiment is the elucidation of the energy transformations of three types of well known energy sources - photovoltaic cell (solar energy to electrical energy), electrolyzer (electrical to chemical energy of hydrogen) and fuel cell (chemical energy of hydrogen to electrical energy) and finding optimal regimes for their maximum efficiencies. The perspective of the improvement of the experiment and its exploitation is given.
