Why does hydrogen gas liberate at Cu electrode in Zn-Cu cell?
In a zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
Is hydrogen power renewable?
Yes. Hydrogen is collected from water in a proses called electrolysis, (we have a lot of water) in electrolysis an electrical current is sent through the water and the hydrogen (negative ions) is sent towards the negative wire. the hydrogen is sent through a protonic stage membrane fuel cell stack where the hydrogen electrons are split from the atomic nuclei and powers what ever needs doing. The electrons bond back with the rest of the atom and then come back out of the fuel cell, bond with oxygen to change back to H2O.
What is the role of electrons in a voltaic cell?
a volcanic cell has electrodes and electrons flow through electrodes .
How do hydrogen cell work?
The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions.The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out. In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.

Can Hydrogen peroxide pass through a cell membrane?
yes, H2O2 passes through cell membrane through passive transport.
How do hydrogen fuel cell cars work?
Hydrogen fuel cell cars are simply electric cars with a different kind of battery. The hydrogen that is stored in a tank runs to the (in this example case) Proton Exchange Membrane, where the hydrogen nucleus, a proton, passes through the membrane, while the electrons must stay behind. To get back to the hydrogen atoms, which are already mingling with oxygen atoms, the electrons pass around the membrane and are captured in an electrical circuit and forced to do work (like run a motor) before they can be reunited with the hydrogen and oxygen. once reunited, the resulting chemical is just hydrogen and oxygen; water.
How does the mitochondrial membrane generate and maintain a H positive gradient?
The passing of the electrons through the membrane complexes allows the protons to leave the cell, then reenters through ATP synthase to fuse with oxygen to form water. Hydrogen ions and the electrons come from NADH and FADH2, which are generated during glycolysis and citric acid cycle.
Does hydrogen fuel cells pollute?
No they don't When hydrogen (electrode in the cell) reacts with oxygen ( catalyst in the cell), it's chemical reaction converts the hydrogen gas to negatively charged electrons (-e) and positively charged hydrogen ions (H+). As for the pollution factor, the ONLY Bi-product from hydrogen cells is Water (H2O). I hope you understood all that (as you would need to know how a battery cell works).
What happens in a hydrogen-oxygen fuel cell?
Oxygen diffuses through the cathode
What happens in a hydrogen oxygen fuel cell?
Oxygen diffuses through the cathode
