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, ...

How does a fuel cell make electricity from hydrogen? What happens in a fuel cell is called an electrochemical reaction. It's a chemical reaction, because it involves two chemicals joining together, but it's an electrical reaction too because electricity is produced as the reaction runs its ...
i hope it doesnt make i hope that heacute i hope they take you i hope this kind of t i hope you realize th i hope your conscienc i hurried to english i hurt much more i i iel i if ignore i iffy i ignored her i ignored the insult i ignored the vibrati i imagine he needs it...
Hydrogen has lots of uses in the world. Scientists have created a catalyst they believe can radically reduce the price needed to create hydrogen. After testing the catalyst for over 10 weeks, they think it can withstand the public's scrutiny.Scientists...
They also help in regulating the concentration of hydrogen ion (pH) in your blood. When you inhale, the diaphragm and intercostal muscles (those are the muscles between your ribs) contract and expand the chest cavity. HowStuffWorks When you inhale, the diaphragm and intercostal muscles (those...
Monolith and Modern Hydrogen are using new technologies to create a cleaner hydrogen that's also creating a byproduct that can be used to make cleaner asphalt. Using carbon, instead of the usual petroleum, makes the asphalt stronger, cheaper and greener. ...
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...
light elements can be used, such as deuterium (an isotope of hydrogen that has a proton and a neutron) and tritium (an isotope of hydrogen containing one proton and two neutrons), and are in fact preferred. This is because in order to fuse two atoms together, theCoulomb forcemust be ove...
In a balanced equation, so two diatomic molecules of hydrogen, and one diatomic molecule of oxygen, creating two molecules of hydrogen.I have to make a model of the reaction, so how would the reactants react to form water? Would it just be heat that accelerates the speed of the molecules...
