Energy Storage - Electrolyzer / Fuel Cell
Background
Like the stored chemical energy in the two components, gasoline and oxygen, that power a car,
it is possible to use other chemical pairs. The combination of hydrogen and oxygen has several
main advantages: The two components are easily produced by the electrolysis of water using
electrical energy. The chemical reaction to get back the stored energy produces only pure water.
It is possible to construct a fuel cell which enables the "cold burning" of the two components
to directly produce electricity. The related Hydrogen(-Oxygen) Technology has the potential
to replace fossil-fuel energy with a renewable storage technology that uses renewable solar
energy sources like wind-power and photovoltaic systems to produce stored chemical energy
for on-demand electricity generation.

FuelCellH2Air - PEM Fuel Cell for Hydrogen / Air Operation
A fuel cell converts the stored chemical energy within hydrogen / oxygen directly into electric energy. It is like a cold burning of hydrogen and oxygen back to water. The key component of the PEM (Polymer Electrolyte Membrane) fuel cell is the MEA (Membrane Electrode Assembly). This is of a Polymer membrane coated on opposite sides with two catalysts that form the anode and cathode of the cell. The basic idea is that the Polymer membrane only conducts positively charged Hydrogen protons (PEM - Proton Exchange Membrane) from the anode catalyst to the cathode catalyst where they combine with Oxygen to form water. So you have a generator with a "charge separation" on the anode and a charge neutralization on the cathode. For the process to work, and in a control manner, there must be an external flow of (hydrogen) electrons via an electrical circuit from anode to cathode. In other words the chemical engine directly generates electricity without any moving parts.
