TRAINER FOR EXPERIENCES ON HYDROGEN FUEL CELLS
This trainer for the study of the fuel cell technology must be specially designed in vertical frames, bench-top and it must be
made of fire varnished metal covered by a coloured polyester glue 150μ 3M7962.
The trainer must be composed of:
· a two-cell electrolysis stack with associated power supply; the two individual cells shall be connected electrically in series;
· a gas storage tank, to which the hydrogen output of the PEM electrolyser stack shall be connected;
· a 10-cell PEM fuel cell stack, with individual cells being wired in series; when the fuel cell stack is supplied with hydrogen, it
shall combine with the ambient to produce current, heat and small quantities of water;
· a solar module, to power supply the electrolysis stack;
· a measuring transformer card for data acquisition and interfacing with the PC where a dedicated software shall process the
data and
draw the characteristic curves;
· a lamp, to be used as a load for the electric energy generated by the fuel cell stack;
· and a pair of two-lamp modules to energize the solar module for indoor use.
On the front panel the following elements must be included:
1. Double cell PEM Electrolyser stack
2. Hydrogen storage tank
3. PEM fuel cell stack
