Phosphoric Acid Fuel Cell PAFC (Phosphoric Acid Fuel Cells) is a fuel cell with phosphoric acid as the electrolyte. In the anode, a hydrogen-rich gas containing CO 2 is passed, and the cathode is introduced with air as an oxidant. Phosphoric Acid Fuel Cell PAFC (Phosphoric Acid Fuel Cells) is a fuel cell with phosphoric acid as the electrolyte.
Phosphoric acid as an electrolyte in fuel cells was discovered in 1961 by Elmer Rey and Tanier and became the electrolyte of choice for fuel cells for power plant power generation in the 70s of the 20th century. Phosphoric acid has many advantages as an electrolyte:
Phosphoric acid fuel cell (PAFC) is the most commercially advanced technology among the hydrogen–oxygen fuel cells. Research on the high-temperature hydrogen fuel cell began in the 1960s leading to the development of PAFCs.
Simple construction, low electrolyte volatility, and long-term stability are additional advantages. Phosphoric acid (H 3 PO 4) concentrated to 100% is used for the electrolyte in this fuel cell, which operates at 150–220°C, since the ionic conductivity of phosphoric acid is low at low temperatures.
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. The components involved in the construction of PAF Cs such as catalyst, electrolyte and bipolar plates will be discussed.
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.
