Il motivo principale è che possono

Il motivo principale è che possono erogare una densità di potenza maggiore di qualsiasi altro tipo di fuel cell. Inoltre possono raggiungere solamente nel giro di 3 minuti la massima potenza erogabile, lavorando a temperature intorno ai 70-85°C. Questo le rende molto versatili ed impiegabili in numerosi ambiti differenti. La chiave di volta di queste celle è ricondotta al particolare elettrolita a base di Nafion, un polimero solido molto simile al Teflon. Per garantire una buona conducibilità agli ioni, tale membrana dev’essere costantemente, ma non eccessivamente, bagnata. Il motivo d’impiego di questa particolare materiale sta nel fatto che non è necessario, come nelle celle Alcaline, di idrogeno purissimo in ingresso. Basta quindi “riformare” qualsiasi altro gas. Si risparmia quindi sulla qualità del carburante in ingresso: infatti come abbiamo visto, i processi di produzione di idrogeno puro possono essere molto costosi. In questo caso basterebbe utilizzare come combustibile l’idrogeno

the main reason is that they can deliver a power density greater than any other type of fuel cell. also can be achieved only within 3 minutes, the maximum output power, working at temperatures around 70-85 ° c. This makes them very versatile and usable in many different fields.the keystone of these cells is attributed to the particular Nafion-based electrolyte, a solid polymer very similar to Teflon. to ensure a good ion conductivity, this membrane must be constantly, but not excessively wet. the reason for use of this particular material is that it is not necessary, as in alkaline cells,of pure hydrogen in input. then just "reform" any other gas. then it saves on fuel quality in input: in fact as we have seen, the processes of production of pure hydrogen can be very expensive. in this case it would be enough to use as a fuel hydrogen

The cornerstone of these cells is traced back to the special electrolyte-based solid polymer Nafion, a very similar to Teflon. To ensure good conductivity, this membrane ion must be constantly, but not overly, wet. The reason for use of this particular material lies in the fact that it is not necessary, as in alkaline cells pure hydrogen. Just then "reform" any other gas. You'll save on fuel quality (input): as we have seen, the processes of producing pure hydrogen can be quite expensive. In this case we use hydrogen as fuel
