Hyosung’s fuel cell system developed through in-house technology, is based on our foundation of environmental preservation.
The fuel cell System generates electricity and heat using the electrical and chemical reaction between hydrogen and oxygen. The electricity, heat, and pure water (H2O) created have 30 to 40 percent power generation efficiency and 45 percent thermal efficiency, for a total of 75 to 90 percent increased efficiency. This type of source is referred to a high-efficiency, renewable energy.
The fuels necessary for power generation through the fuel cell system are hydrogen and oxygen. For power generation from the fuel cell to occur, hydrogen is first isolated from fuels such as city gas, LPG, and kerosene; this isolated hydrogen is used as a fuel in the positive (+) pole in the fuel cell system and the oxygen in the air is supplied as the negative (-) pole. The hydrogen fuel is separated to become a hydrogen (H+) ion and an electron (e-) at the positive (+) pole via a catalyst. The hydrogen ion moves through the electrolyte layer and the electron (e-) moves to the negative (-) pole through the electric circuit. The hydrogen ion (H+) and the electron (e-) are combined with the oxygen at the negative (-) pole and the resulting material is water (H2O). In this process, the electric energy in the electron generates the electricity while passing through the circuit while the heat is generated as a result of the chemical reaction.
Hyosung’s 1kW Low Temperature PEMFC System uses residential gas
and generates both electricity and hot water with minimized CO₂and high energy efficiency
Hyosung’s High Temperature Fuel Cell Systems, currently in development, feature a high generation efficiency and wider usage range for heat generated than the low temperature PEMFC.
