The Fuel Cell Energy Training System RVX 123A is an educational apparatus for investigating polymer-membrane fuel cells with direct chemical-to-electrical energy conversion. This fuel cell energy training system operates in combined heat and power generation with 200W nominal output, hydrogen from pressure vessel, and oxygen from ambient air, controlled via integrated electronic load.
Product Overview
The RVX 123A fuel cell energy training system features a 200W nominal output polymer-membrane fuel cell with voltage range 13.75 to 23.75V and current 13.3 to 16.6A. Hydrogen supply uses standard pressurized vessel with high-pressure reducing valve and solenoid valve. Oxygen draws directly from ambient air. Integrated 250W electronic resistive load controlled via touch LCD allows precise operating point adjustment. Thermal energy from cell cooling dissipates through cooling circuit and integrates into instrumentation analysis. Water separator collects accruing water with configurable purge valve in dead-end mode. Moisture regulation occurs automatically via operating temperature and air flow without external humidification. All measured values transmit to PC via included DAQ system and LABVIEW software.
