Fuel Cell Power Generation Business

In line with Korea’s energy transition policy and hydrogen economy roadmap, GnCenergy is accelerating the shift from fossil fuel-based energy to clean hydrogen power.
Building on the exceptional expertise developed through its emergency generator business, GnCenergy is cultivating fuel cell power generation as a high-value growth business for sustainable expansion.

Core Fuel Cell Model

SOFC

  • Solid Oxide Fuel Cell
  • Solid Oxide Fuel Cell
  • Best-in-Class Power Generation Efficiency

    Highest electricity generation efficiency
    among existing fuel cell technologies (over 60%)

  • High-Temperature Operation

    Operates at high temperatures of 600–1,000°C,
    and produces very little noise due to the absence of a combustion process

  • Key Applications

    Large-scale utility-level power plants (e.g., Seokmun Green Energy)

PAFC

  • Phosphoric Acid Fuel Cell
  • Phosphoric Acid Fuel Cell
  • Technological Maturity

    A highly proven technology with a long track record of commercialization, offering outstanding reliability and durability.

  • Combined Heat and Power (CHP) Efficiency

    Heat (hot water) generated during electricity production used for industrial applications and district heating, maximizing overall system efficiency.

  • Key Applications

    Small fuel cells in the distributed generation and HPS market

Comparison of Energy Efficiency by Technology
