Improvements in or relating to fuel cells

摘要

A fuel cell is described having ammonia as the input fuel and an iron based catalyst. An yttria stabilized zirconia electrolyte is used as a solid oxide electrolyte. The ammonia fuel is broken down into hydrogen in the cell, the hydrogen being used in the electrolyte to generate electrical power. Ammonia is suggested as a fuel as it is a common biogas and has many advantages in safety terms over hydrogen.
