Fuel Cells Energy Weight Cost Device that converts chem pelented energf energy stored in molecular bonds Jints electrical energy without Combustion. * Chige sped & Lifespan × Malarials They offer bigher electrical efficiency (240) conventional Principle of operation Device that uses th (or th rich fuel) Cy O₂ to create electricity by an electrochem process. ½ cy fair) are suppled to anode ty Cattrode respectively. when bydrogen is eld to anode, hydrogen molecules are split into prolon by e. Protons imigrate thru ile thru electrolyte where they react with to cathode, 02 to form water. Simultaneously, és are forced to travel around the electrolyte to cathodesicle, because they can't pan through electrolyte. This survement thus creates electrical current.
