What is it and how does it work? What is a PEM fuel cell? The Fuel Cell
Image of page 2
A fuel cell is a device that through an  electrochemical process converts hydrogen and  oxygen directly into water. In this process energy  is released in the form of electricity and heat. The  chemical process is electrolysis in reverse. In  the  PEM  fuel  cell,  hydrogen  molecules  are  oxidised  at  the  anode  to  positively  charged  hydrogen ions, protons, releasing electrons to the  cathode via an external electric load. The protons  diffuse  through  an  ion-conducting  membrane,  to  the cathode. At the cathode oxygen combines with  the electrons and the protons to form water. The  The Fuel Cell
