Climatic PEM Fuel Cell System Testing — up to 250 kW

This test bench is a climatic PEM fuel cell system test rig located in the Basque Country, Spain. Designed for complete Balance of Plant (BoP) system testing up to 250 kW, it includes a 22 m³ walk-in climatic chamber (−40 °C to +90 °C with humidity control) — one of the few European facilities capable of full system testing at this power level under climatic conditions.

This bench is the right choice for system integrators, OEMs and Tier-1 suppliers who need to prove a complete fuel cell powertrain works under real-world ambient extremes — from arctic cold-starts to high-humidity hot climates.
