Poison-Tolerant Fuel Cells

摘要

Afuel cell electrode has three functions: allow access to reacting gases, provide active electrocatalytic sites, and allow transport of electrons as well as ions (1). High-temperature fuel cells generate electrical power by oxidizing the fuel electro-chemically rather than by chemical combustion. They achieve this by digesting carbon-based fuels with the help of an internal catalyst. However, sulfur in the fuel gas is a potent poison for the nickel electrocatalyst used in the anodes of such cells currently.
