The standard NextCell configuration is designed for stability and reproducibility, particularly in the 750°C – 850°C range.

• Support: 150 um thick Hionic™ (Scandia-Stabilized Zirconia). It is ~4x stronger than standard YSZ-8, allowing it to survive the mechanical clamping of test fixtures.

• Anode: Typically a multi-layer NiO-GDC / NiO-YSZ (~50 um).

• Cathode: Standard NextCells use LSM/LSM-GDC, while the "HP" (High Performance) versions often use LSCF or LSC for better low-temperature activity.

• Active Area: Usually 1.25 cm² on a 20 mm or 25 mm diameter disk.

Since the anode contains Nickel Oxide (NiO), it must be reduced to Nickel (Ni) to become electrochemically active.

1. Heat Up: Ramp at 2°C/min to 800°C in stagnant air or flowing N2 (on the anode side) and Air (on the cathode side).

2. Reduction: * Once at 800°C, introduce a dilute fuel mix (e.g., 5% H2 in N2).

   • Hold for 30–60 minutes.

   • Gradually increase to 100% H2 (typically humidified with 3% H2O via a bubbler at 25°C).

3. OCV Check: A healthy NextCell at 800°C with 100% wet H2 should yield an OCV of ~1.1 V.
