Fuel cell
A fuel cell is a system that converts chemical energy into electricity through a chemical reaction between a fuel (often hydrogen) and an oxidizing agent (often oxygen). Fuel cells offer a sustainable energy solution with the potential to power everything from vehicles to entire energy grids with minimal environmental impact.
Requirements
Withstand pressures from 1 to 4 bars
Deal with temperatures 20°C to 100°C (LT-PEM) and up to 220°C (HT-PEM)
High purity and cleanliness (no leachable and extractables that would poison the catalyst)
Chemical resistance against hydrogen, sulfuric acid (LT-PEM), phosphoric acid (HT-PEM), hot air and water
Low hydrogen permeation rate
