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).
the cell needs to be able to change in a environment that is als changing.
The cell environment refers to the internal conditions within a cell, including factors like temperature, pH, and chemical concentrations. These factors are tightly regulated by the cell to maintain optimal conditions for cellular processes to occur. Any disruption in the cell environment can affect the cell's ability to function properly.
negatively charged
Water is the benefit of a hydrogen fuel cell ;)
A hydrogen fuel cell is a type of electrochemical cell that produces electricity by combining hydrogen and oxygen to generate power. The key difference is that in a hydrogen fuel cell, the reactants (hydrogen and oxygen) are continuously supplied externally to sustain the electricity generation process, while in a typical electrochemical cell, the reactants are contained within the cell and eventually get depleted.
Hydrogen engines.
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.
A living cell is much larger than an atom of hydrogen. A living cell can be as much 10,000 times larger in size compared to a single hydrogen atom.
The interior surface of a cell membrane of a polarized neuron is negatively charged due to the presence of large molecules like proteins and nucleic acids. This negative charge creates an electrical gradient that helps maintain the resting membrane potential of the neuron. In contrast, the external environment is more positively charged in comparison.
Using a cell phone during your daily life does not in itself harm the environment. Cell phones use radio waves at very low power to communicate and have never been proven to have an affect on humans or the surrounding envirnoment. The biggest impact on the environment comes from the manufactor and eventual disposal of the cell phone, the battery and other accessories.
There are no commercially available hydrogen fueled cars.
