The reasons to become the next generation energy
-The technology directly transforms fuel cells into energy. It shows 10~20% higher efficiency, compared to the existing method.
-The fuel energy technology reaches 80% of energy efficiency as 40% of electricity and 40% of heat energy. It is able to use both energy types simultaneously
Green generating process
-Hydrogen and oxygen as the raw materials are harmless, and the transformed material, water is also innocuous.
-Carbon dioxide, emitted during the transforming process, is less than a thermal power generation.
The process diagram of the fuel cell system
-Reformer : The device catalytically reacts fossil fuels, and transforms them into reformed gas. The gas is injected into fuel cells.
-Stack : The device generates energy by an electrochemical method between hydrogen from Reformer and Oxygen
-Electricity inverter : The device changes direct current, coming from fuel cells, to inter current.
Reformer for hydrogen supply
Partial Oxidation (POX)
Since the reaction is incomplete combustion between fuels and oxygen, the reaction arouses heat, and it keeps high temperature. Because the process uses Oxygen, hydrogen concentration is maintained at 30~40%.
Steam Reforming (SR)
The power generation method by natural gas and steam is the most economical means, since the hydrogen production efficiency is higher than 70%.
Autothermal Reforming (ATR)
Partial Oxidation (POX) and Steam Reforming (SR) occur at the same time. Therefore, this system can be operated without heat supply from outside.
Sulfur in town gas should be eliminated, since reforming catalysts can be contaminated by sulfur, and it can cause deactivation.
Primary Process :
Separation of fuels in the hydrocarbon line for reforming process.
The fuels are separated into Hydrogen and Carbon.
Selective Oxidizer :
Decreasing carbon monoxide to several ppm by means of using air to supply reformed gas into stacks.
Steam Generator :
Heating water to supply steam for the reforming process.
Steam-Methane Reforming Mechanism
It is an energy transforming technology from a chemical reaction between hydrogen and oxygen to electric power without emitting pollutants. Environmentally friendly and high-efficiency technology.
From hydrogen on the anode and oxygen on the cathode, it generates energy as a reverse reaction of electrolysis. The type of the energies are electricity and heat.
The main source comes from town gas (LNG, LPG), Biogas and so on, and transform them to hydrogen. Since then, the technology is not limited by geographical factors. It can be used not only for electricity, but for also hot-water supply and heating.
