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), electrolyser (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
Highlights
The energy is one of the most important physical quantities, but in the general sense it constitutes one of the most vital topics in contemporary society [1]
In the last part of the paper we show the measured data and their evaluation of the individual energy transducers, characterized by their energy transformation efficiencies (solar cell, electrolyser and fuel cell (FC))
Electrical energy obtained in the first energy transformation step is transformed in the following step into the chemical energy in the form of hydrogen and oxygen by the process of electrolysis
Summary
The energy is one of the most important physical quantities, but in the general sense it constitutes one of the most vital topics in contemporary society [1]. Little is known and still less is taught at all types of schools about functioning, for society vital, devices that serve as transducers of one type of the energy to another and/or means for energy storing [2]. The purpose of the present work is the characterization of several well known energy transducers using interactive remote experiment (RE) “Energy transformation” (http://remotelab10.truni.sk). We give briefly the construction of the RE with the set of energy transformation devices, followed by its technical realization and brief description of the corresponding physical basis. In the last part of the paper we show the measured data and their evaluation of the individual energy transducers, characterized by their energy transformation efficiencies (solar cell, electrolyser and fuel cell (FC))
