This option of the Hydrogen Fuel Cell Trainer can work in off-grid mode. It consists of a hydrogen cylinder, PEM fuel cell stack, DC-DC converter, load, pressure meter, flow meter, etc. The trainer allows investigating the main principles of fuel cell operation and its characteristics. The students will learn how hydrogen and air reactions can produce electrical energy.
The fuel cell stack uses ambient air. The hydrogen cylinder should be refilled with 99.99% purity hydrogen by the user.
