Introduction to Phosphoric Acid Fuel Cells

Phosphoric acid fuel cells utilize phosphoric acid as the electrolyte to facilitate the electrochemical reaction between hydrogen and oxygen, producing electricity, water, and heat. They are categorized as high-temperature fuel cells, typically operating at temperatures between 150°C and 220°C (302°F to 428°F). PAFCs are primarily used in stationary power generation applications due to their ability to provide continuous and reliable energy.

Key Features of Phosphoric Acid Fuel Cells

1. Efficiency

PAFCs are known for their relatively high electrical efficiency, typically ranging from 40% to 50%. When waste heat is utilized in a combined heat and power (CHP) configuration, the overall efficiency can exceed 80%, making them an attractive option for commercial and industrial applications.

2. Durability

With a robust design, PAFCs can operate for long periods without significant degradation, providing a reliable power source for continuous operation. This durability is particularly advantageous for applications requiring uninterrupted power supply.
