Welcome to our new Hydrogen Weekly podcast, we hope you enjoy it. This week we will be discussing “fuel cells”. It was Welsh scientist Sir William Grove who in 1839 discovered the principle of producing electricity from an electro-chemical reaction between hydrogen and air. He called it the ‘gas battery’, though what we now know as the fuel cell wasn’t really a feasible electricity producer until the mid 20th century. Hydrogen fuel cell vehicles combine the range and refuelling of conventional cars with the recreational and environmental benefits of driving on electricity. Refuelling a fuel cell vehicle is comparable to refuelling a conventional car or truck pressurised hydrogen is sold at hydrogen refuelling stations, taking less than 10 minutes to fill current models. Compared with battery-electric vehicles—which recharge their batteries by plugging in—the combination of fast, centralised refuelling and longer driving ranges make fuel cells particularly appropriate for larger vehicles with long-distance requirements, or for drivers who lack plug-in access at home.
