Hydrogen gas is separated by a catalyst at the anode in a fuel cell into protons and electrons. The protons pass directly through a proton exchange membrane, while electrons are forced through an external circuit, ...
That might sound weird, but it's just the way the chemistry plays out: dissolved CO2 molecules combine with water to form what's called carbonic acid, which in turn combines with carbonate to form hydrogen carbonate.可能有点危言耸听，但这是化学物质本身的特性所造成的，溶解的二氧化碳与水结合形成...

Batteries and renewable energy alone can’t decarbonize industries, and recent proposals for a “hydrogen economy” could bridge those gaps.
National Fire Protection Association. Violating these code provisions can result in hefty fines and fees, not to mention the public health and safety risk posed by volatile hydrogen. Unlike substances like natural gas, hydrogen is odorless and colorless, which can make it tough to detect any ...
Hydrogen production and storage as the core of novel hydrogen economy attract extensive attentions in both industry and academia. Methanol﹊nvolved hydrogen production has been considered as an alternative strategy towards conventional methane stream reforming owing to its milder reaction condition and ...

How do hydrogen fuel cells work? Hydrogen fuel cells work by separating hydrogen into protons and electrons. The protons pass through a membrane, while the electrons create a separate current that can be utilized before they rejoin with the protons and oxygen to produce water. What are the main...
hydrogen tanks using petrol-powered trucks would negate some of the advantages of using hydrogen in the first place. So fleets of electric trucks powered by electricity from renewable sources – or hydrogen – would ideally need to materialise before widespread distribution of hydrogen would make ...
The Pacific Northwest National Laboratory says it’s about two years away from making hydrogen fuel cell cars more cost-effective — a 20-plus-year journey that once included a dream of going to Mars. Researchers at the lab in Richland, Wash., have been working on a solar-reflector-based ...
