This video podcast gives a brief introduction. These cells like all electrochemical cells are essentially reliant on a redox reaction ie exchange of electrons. In Western Australia, along with other parts of the world, hydrogen fuel celled buses are being trialled. I have written a lot of educational materials for teachers and students based on the Western Australian trial. These materials have been used by teachers and students in many countries and can be located for download at http://www.gdc.asn.au/ecobus/ .
