An electrolyser is Adidas iPhone
5 Cases For Salea piece of scientific equipment that splits polarised
molecules into its ions. In this case it will split water into hydrogen and
oxygen gas. A dry cell electrolyser is an electrolyser that is completely
enclosed; the other type is a wet cell electrolyser which can be two metal
plates in a bowl of water. The equipment is fairly simple but the theory behind
it is a bit more

iPhone 5S Cases complicated, if you not interested in the theory then
skip to step 1.
Here the theory: the electrolyser uses the different ionic charge on the different atoms in the molecule to split it into its respective charged atoms or
molecules, for example, water gets split into Hydrogen and Oxygen because in the
water molecule the hydrogen is slightly positively charged and the oxygen is
slightly negatively charged. These

casescharges are only very slight, +1 electron volt (ev) for each
hydrogen and 2 ev on each oxygen atom. Just for comparison 1 electron volt is
1.6 Coulombs © and 1 Coulomb is the charge transported by a steady current of
one ampere in one second. The hydrogen is attracted to the negatively charged
electrode or Cathode and the oxygen is attracted to the positively charged
electrodes or Anodes. At the anodes the oxygen ions loose an electron and bond
to form oxygen gas, at the cathodes the hydrogen ions get an electron from the
cathode and then bond to form hydrogen gas. This transfer of electrons from and
to the electrodes completes the circuit and allows current to flow. A catalyst
can be used to make the process more efficient by reducing the energy needed to
start the process; the catalyst that I use is sodiumhydroxide in a 1 to 40

cases mix with deionized water. The water doesn need to be deionized
but it extends the lifetime of the unit as minerals and other stuff won build up
on the electrodes.
