Another advantage to the PAFC is that the phosphoric acid electrolyte can operate above the boiling point of water. A disadvantage of the PAFC is that, when compared to other fuel cells of similar weight and volume, it produces less power.
Phosphoric acid fuel cells (PAFCs) consist of an anode and a cathode made of a finely dispersed platinum catalyst on carbon and a silicon carbide structure that holds the phosphoric acid electrolyte. They are quite resistant to poisoning by carbon monoxide but tend to have lower efficiency than other fuel cell types in producing electricity.
Phosphoric acid fuel cells have developed more slowly than other fuel cells due to the low conductivity of acid. G.V. Elmore and H.A. Taner experimented with this type of fuel cell in 1961, using an electrolyte consisting of 35% acid and 65% silicon powder glued onto a Teflon card. PAFC works with air, not oxygen.
Phosphoric acid provides numerous advantages: the required thermal, chemical, and electrochemical stability; low volatility (which other inorganic acids do not possess); and the absence of the CO 2 reaction to form carbonate ions.
This is due to the fact that the platinum catalyst used in the cells is Jung et al., 2013). Phosphoric acid fuel cells (PAFCs), on the other hand, do not have such a requirement as hydrogen can be generated in -situ from methanol (or similar li quid fuel). This 2017). including the thermodynamics of the cell.
