Like battery-powered electric cars, fuel cell vehicles have electric motors.
The hype around hydrogen fuel cells has died down, but scientists have continued to pursue new technologies that could enable such devices to gain a firmer foothold.
Hydrogen represents a possible sustainable fuel source when it is produced from water and burned with oxygen because only water is released as a by-product.
Among the cleanest low-carbon fuels is hydrogen, which can react with oxygen to release energy, emitting nothing more harmful than water (H2O) as the product
Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen – the cleanest source of energy.
UNSW Sydney chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel.
