Le macchine termiche, per via del l

Le macchine termiche, per via del loro specifico funzionamento, hanno maggiori dispersioni termiche alle basse temperature. Infatti esse devono prima convertire l’energia chimica del combustibile in calore e successivamente in lavoro. Per ovviare a tali dispersioni sarebbe necessario lavorare a temperature molto più elevate, non però raggiungibili per via dei limiti strutturali dei materiali. Le celle a combustibile invece traducono l’energia chimica direttamente in lavoro (elettricità), e quindi le perdite sono molto limitate. Per questo motivo si avranno risultati in efficienza nettamente superiori rispetto alle tecnologie tradizionali, con valori che possono raggiungere la soglia dell’80%.

Risultati (Inglese) 1:

thermal machines, because of their specific operation, have greater heat loss at low temperatures. In fact, they must first convert the chemical energy of the fuel into heat and then into work. to overcome such dispersions would be necessary to work at much higher temperatures, however, not reached because of the structural limits of the materials.fuel cells instead translate the chemical energy directly into work (electricity), and thus the losses are very limited. for this reason it will result in much higher efficiency than conventional technology, with values ​​that can reach the 80% threshold.

Thermal machines, because of their specific operation, are more heat loss at low temperatures. In fact they must first convert the chemical energy of the fuel into heat and then to work. To avoid such disturbances would need to work at much higher temperatures, but not just because of the structural limits of the materials. Fuel cells instead translate chemical energy directly into work (electricity), and then the losses are very limited. For this reason you will have results in much higher efficiency compared to traditional technologies, with values that can reach the threshold of 80%.

For this reason, there will be results in efficiency significantly higher than traditional technologies, with values that can reach the threshold of 80 %.
