Proton exchange membrane fuel cells (PEM FC) use hydrogen fuel and oxygen to produce elec-tricity to power automobiles. Ammonia borane is a hydrogen source used to fuel these cells. The hydrogen atoms can be removed from the ammonia borane molecule by either hydrolysis or thermolysis. Hydrolysis has a low hydrogen yield and the ammonia borane cannot be easily regenerated from the reaction byproduct. The thermolysis byproduct can be used to regener-ate ammonia borane, but it generally requires very high temperatures or expensive additives. A new method of thermolysis, developed at Purdue University, produces a high yield of hy-drogen for PEM fuel cells without requiring ad-ditives or extreme temperatures. This provides an excellent fuel source for PEM FCs. Since PEM fuel cells are used in automobiles, this could be a possible alternative to fossil fuels.
