Scientists have successfully engineered a fatigue-resistant electrolyte membrane that exhibits resistance to cracking and significantly extends the lifespan of fuel cells. Credit: oakridgelabnews CC BY 2.0
A novel approach to address environmental challenges is developing and commercializing robust hydrogen fuel cells. These cells contain a polymer electrolyte membrane that serves as a barrier between the electrodes (the conductors that enable the flow of electricity through a substance). This membrane conducts protons but inhibits the movement of electrons, hydrogen molecules, and oxygen molecules.
When a vehicle speeds up or slows down, the fuel cell operates inconsistently, leading to varying water production and …
