Fuel Cell Technology
Fuel Cell Technology unlocks Energy Cell Factory charging and improves Fuel Cell generation and capacity.
Quick stats
| Effect at level 1 | Bonus |
|---|---|
| Fuel Cell charging and finite storage | +10% |
Level 1 unlocks charging and adds 10%; later levels follow tier progression. A fueled Energy Cell Factory supplies charge at 1 Fuel Cell per 80 factory output before charging modifiers. Factory output does not feed the live grid; power deficits can still drain cells.
Cost and access
Available from level 0 without a lab or research prerequisite. Level 1 costs 32 base RP; later levels grow exponentially before any other-domain tier surcharge. The Research screen shows the current quote and saved funding.
Purchase a completed level immediately with RP, or use automatic investment. Metal, crystal and deuterium are not research payments in 3.0. Physical Research Labs increase RP income, not purchase speed.
Each fifth level adds another initial amount before compounding the bonus itself by 1%. See tier progression.
When to invest
Complete level 1 before depending on scans, Jump Gates or Fuel Cell boosts. Keep the Energy Cell Factory fueled and active with room in storage; positive grid energy is not required for charging, although a deficit may drain stored cells. Research alone produces no charge.
