Fuel cells generate electricity by combining hydrogen (or other fuels) and oxygen electrochemically, producing water and heat. Proton exchange membrane (PEM) fuel cells are prominent in transportation, offering high efficiency and zero emissions if hydrogen is from renewable sources. Challenges include catalyst costs (often platinum) and hydrogen storage. Fuel cells are a key technology in the transition to cleaner energy systems.
