Power density
3-chamber photosynthetic MDC with C. vulgaris algae biocathode treating real landfill leachate, mid-range factor-conditions (FC) for external resistance / pumping rate / temperature / light / DO. Headline number from abstract: "maximum power density of 121.57 mW m⁻² (anodic volume)". Anchors the algae-sub-regime power ceiling — pairs with Salgado-Hernández 2021 current_areal anchor (1.2 A/m²) on the same Rint / CE / OCV branch parameters.
DB extraction (paperId cmcva3cxr00xvrc9dq8kpjue0, confidence 0.5): maxPowerDensity = 121.57 mW/m². Abstract phrasing: "a maximum power density of 121.57 mWm−2 (anodic volume) and an average desalination rate of 3.93 mg/L/h".

What we don't know about this paper (4 items)
Wave 1.5 calibration preset (2026-05-22, codex P1) — added as the 2nd algae-sub-regime anchor after the Salgado-Hernández anchor was corrected from 0.12 → 1.2 A/m² (mA/cm² unit-conversion fix). Source: local Supabase DB query (paperId cmcva3cxr00xvrc9dq8kpjue0, confidence 0.5 on maxPowerDensity).
Confidence 0.5 on the power_density extraction. Abstract clearly states "121.57 mWm⁻² (anodic volume)" but the closure-relevant config details (exact COD, HRT, electrode area, salinity) are NOT pinned in the abstract — we pick bench MDC defaults matched to the Salgado sister-anchor. The algae sub-regime is current-limited by photosynthetic O₂ supply at the cathode, so the anode-side defaults are not the dominant fit lever.
Anchor on `power_areal`, not `current_areal` or `coulombic`. Abstract does not cleanly report a peak current density or system CE. The branch model predicts both current AND power from the same underlying Rint/CE/OCV parameters, so a power-only anchor still constrains the branch — pairs with Salgado-Hernández current_areal / CE anchors on the same branch.
Landfill leachate is a real, complex anolyte (NOT defined medium). The closure label `culture_type: wastewater_inoculum` is the closest match; landfill-leachate-specific anode kinetics (heavy metals + recalcitrant organics) are NOT modeled — the algae cathode is the dominant lever for this anchor.
