Fuel cells have received much attention recently in the media, public and even some politicians. Back in 2003, President Bush announced the Hydrogen Fuel Initiative during a State of the Union address. Well, I’ll take my time in this article, how fuel cells work and explain their basic components.
These devices convert chemical energy into electrical energy. They use hydrogen and oxygen to produce the chemicals to electricity and water.
It is the negative aspect of the cell. It conducts the electrons that are freed from hydrogen molecules to an external circuit. In addition, hydrogen gas is uniformly distributed on the catalyst surface.
This is the positive element of the cell. It channels the electrons from the external circuit to the catalyst, where they are with hydrogen ions and oxygen recombine to form water.It also distributes oxygen to the catalyst surface.
This is the proton exchange membrane. This is a special material that conducts only positively charged ions. The membrane is there to block electrons. This membrane must be hydrated to function and remain more stable.
It is the material that facilitates the reaction of oxygen and hydrogen. The catalysts are typically rough and porous so that the maximum surface area of ??platinum for hydrogen or oxygen may be suspended. Side coated with platinum catalyst faces the membrane mentioned above.
How fuel cells work?
The hydrogen pressure in the cell on the anode side of the cell. When the hydrogen contacts the platinum catalyst, they split into two hydrogen ions and two electrons. These electrons through the anode, where they are transported in the external circuit and back on the cathode side of the cell produced. The released electrons provide the current to the motor.
On the cathode side of the cell, oxygen through the catalyst where it is separated into two oxygen atoms forced. These atoms have a strong negative charge. This negative charge attracts the two hydrogen ions across the membrane. If hydrogen and oxygen combine, they form water. Cells makes environmentally friendly.
This reaction in a single cell typically produces 0.7 volts. To increase the power must be many individual cells are combined in a fuel cell. other fuel cells split hydrogen gas into the HHO gas or explosive gases, increasing power for car engines.
