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 have been the first type of fuel cells that were commercialized in the 1970s. PAFC use H 3 PO 4 as the electrolyte between the anode and the cathode . PAFCs are very reliable with the mean time before failure over 2500 h. ... ...
Phosphoric acid fuel cells (PAFC) are a type of fuel cell that uses liquid phosphoric acid as an electrolyte. They were the first fuel cells to be commercialized. Developed in the mid-1960s and field-tested since the 1970s, they have improved significantly in stability, performance, and cost.
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 fuel cells (PAFC) currently represent one of the fuel cell technologies that have been demonstrated in many countries around the world and for many applications. PAFCs can be purchased, complete with a warranty, maintenance and spare parts service.
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.
