PAFC

What is the power output of PAFC?

The phosphoric acid fuel cell (PAFC) is one of the few commercially available batteries. Hundreds of these batteries have been installed around the world. Most of these provide power ranging from 50 to 200 KW, and also 1 MW and 5 MW power plants have been built.

How does a PAFC work?

A phosphoric acid fuel cell (PAFC) applies liquid-form phosphoric acid as the electrolyte to transfer charge mediators (H+). This system can only work at relatively high temperatures (around 200 °C), because phosphoric acid solidifies at lower temperatures.

Why PAFC is unsuitable for use in car?

If gasoline is used, the sulfur must be removed. At lower temperatures phosphoric acid is a poor ionic conductor, and CO poisoning of the platinum electro-catalyst in the anode becomes severe. However, they are much less sensitive to CO than PEMFCs and AFCs.

Is PAFC tolerant to CO2?

2 Phosphoric Acid Fuel Cells. The PAFC are the most developed at commercial level for megawatt range (up to 25 MW); it is very tolerant of CO2 presence in the air stream (Carrette et al., 2001). The liquid electrolyte is stabilized in a solid matrix of silicon carbide as shown in Figure 4.27.

Why phosphoric acid is used in fuel cell?

Phosphoric acid has many attractive properties as a fuel cell electrolyte such as (1) stability, even at 200 °C; (2) low vapor pressure, although not negligible; (3) ability to use air as the cathode reactant gas; and (4) tolerance to carbon monoxide (200 °C operation).

Why phosphoric acid fuel cell is suitable for use in cars?

What is phosphoric acid fuel cell used for?

Phosphoric Acid Fuel Cell This type of fuel cell is used in stationary power generators with output in the 100 kW to 400 kW range to power many commercial premises around the world, and they are also finding application in large vehicles such as buses. Most fuel cell units sold before 2001 used PAFC technology.

What fuel is used in fuel cells?

hydrogen
Most fuel cells are powered by hydrogen, which can be fed to the fuel cell system directly or can be generated within the fuel cell system by reforming hydrogen-rich fuels such as methanol, ethanol, and hydrocarbon fuels.

Which kind of fuel does not require oxygen?

Nuclear fusion
Nuclear fusion does not require oxygen. In fact, you don’t need any other material at all. You just need enough pressure or heat to squeeze the nuclei of the atoms close enough that they overcome their electrostatic repulsion and bond into a single nucleus.
