ABSTRACT
A fuel cell converts the chemical energy in a fuel into electricity by reacting it with oxygen or another oxidising agent. Auto-manufacturers are investing billions in developing fuel cell vehicles and even in launching the necessary infrastructure. Reducing the amount of expensive platinum used by polymer fuel cells would reap further cost reductions. The fuel for this novel fuel cell, hydrazine hydrate is a nonflammable, high energy density fuel that can be stored in a technically safe manner. Maybe hydrazine hydrate is a game-changer. But at the moment, hydrogen is the most common fuel because platinum-containing proton exchange membrane fuel cells are the most common fuel cells. Hydrogen, the simplest chemical element, reacts with oxygen, releasing heat that can be used in an engine or a fuel cell. The United Kingdom government believes that the use of hydrogen as a fuel and energy storage medium has a significant future in the country.
