2024 Hyzon VLIII200-50 200KW Rated Power Fuel Cell System - Hydrogen Fuel Cell

What capacity and product purity does it produce?

This is a power generation fuel cell system, not a production unit—it consumes hydrogen to produce 200 kW of electrical power at 250-500V and 0-800A. Fuel cells typically require hydrogen purity of 99.97% or higher (ISO 14687 Grade D) to prevent catalyst poisoning and membrane degradation from contaminants like CO, sulfur compounds, and ammonia.

How long was it in service, how long has it been down, and how was it preserved?

These units are listed as new with 2024 serial numbers, suggesting zero or minimal operating hours. The listing does not indicate whether the fuel cells have been wet with coolant or exposed to hydrogen, or what storage protocols have been followed. Ask the seller for actual run hours, any test cycles performed, storage environment (temperature and humidity), and whether membrane hydration or nitrogen purging procedures have been maintained—fuel cell membranes can degrade if allowed to dry out or if contaminants enter during storage.

What is realistically involved in relocating and re-erecting it?

The listing notes this system offers 30% lower weight and volume compared to typical 200 kW fuel cells but does not provide actual dimensions or weight. Request exact weight, dimensions, and any special handling requirements—fuel cell stacks are vibration-sensitive and may require shock-mounting during transport. Installation typically involves hydrogen supply integration (pressure regulation, safety sensors, ventilation), coolant loop connection, electrical integration with appropriate DC bus or inverter, and commissioning that includes leak testing, purging protocols, and polarization curve verification.
