The 4-cell solar panel is used for experiments with photovoltaics and for generating electric energy for the electrolyzer. It can be turned in its frame for easier alignment towards a source of light.
The electrolyzer separates water into hydrogen and oxygen. Due to PEM technology, it is operated with distilled water and requires no caustic solutions or acids. The integrated graduated gas storage canisters visualize the classic water separation experiment, as with the Hoffmann apparatus.
The powerful double fuel cell is used to generate electricity from hydrogen and oxygen. The two fuel cells can be connected in parallel and in series. It is based on PEM technology, which is the most widespread technology used in the development of fuel cell applications, such as
for motor vehicles or stationary power supply systems.
The load module is used for the specific loads to the fuel cell and solar panel by a motor, a lamp or 10 selectable resistors. The resistors are optimized for measuring the characteristic curve of the solar panel and fuel cell.
The measuring unit has two measuring ranges for current and voltage. The measured values are clearly readable on large LED displays. In addition, analogue data output enables further processing of the recorded data.
