Gas guzzlers reborn: Why your next car could run on hydrogen
“Now, there are signs of a comeback. A recent survey of more than 900 global automotive executives by consulting firm KPMG found that 52 percent rated hydrogen fuel cell vehicles as a leading industry trend. Japan has announced plans to put 40,000 hydrogen vehicles on the road in the next five years, and South Korea 16,000. Germany wants to have 400 refuelling stations for hydrogen vehicles by 2025 and California has already opened 35.”

Fuel Cells
“Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode.”

Toyota plans to expand production, shrink cost of hydrogen fuel cell vehicles
“TOYOTA CITY (Reuters) - Toyota Motor Corp (7203.T) is doubling down on its investment in hydrogen fuel cell vehicles, designing lower-cost, mass-market passenger cars and SUVs and pushing the technology into buses and trucks to build economies of scale.”
