Description
Technical field
The utility model belongs to teaching aid field, is specifically related to a kind of hydrogen-oxygen fuel cell demonstration teaching aid.
Background technology
Fuel cell is a kind of chemical cell, and it utilizes the energy disengaged during material generation chemical reaction, is directly transformed to electric energy.From this point, it with other chemical cells if zinc-manganse dioxide dry cell, lead accumulator etc. are similar.But need continuously to its supply response material---fuel and oxygenant during its work, this is not quite the same with other general chemistry batteries again.Because it fuel is become electric energy by the energy that chemical reaction disengages export, so be called as fuel cell.Specifically, fuel cell is " generator " of the reversed reaction of the electrolysis utilizing water.It is made up of positive pole, negative pole and the electrolyte panel be clipped in the middle of both positive and negative polarity.
The complex structure of fuel cell, not easily understands during Students ' Learning, and the teaching aid at present on the market about fuel cell is also less.
