SOFC is long-term fuel-cell winner.
Solid oxide fuel cells have better electrical efficiency and are the long-term technology direction, even though they are less mature than PAFC. As data-center power demand and technology advance, SK Eternix and MiCo's subsidiary are better positioned over time.

Doosan Fuel Cell wins on data-center power.
Data-center onsite power demand makes fuel cells attractive: fast supply, decent output, low carbon, easy construction, and flexible modular scale. PAFC is a proven technology, and Doosan Fuel Cell is the representative PAFC player. If it wins orders properly, target prices point to 58,000-70,000 won; for a conservative entry, the speaker suggests using a deep discount to target. Near-term fuel-cell momentum is attractive.

Korean nuclear pullback is mid-term correction.
The nuclear renaissance is starting, with eight US reactor units and a new Korean nuclear cycle from October; APR1400 is cheaper than AP1000 and supports larger order values, so the recent pullback in Korean nuclear names is a mid and long-term correction, with KEPCO E&C specifically geared to APR1400.
