The Fuel Cell Energy Training System RVX 123 is a comprehensive educational apparatus for investigating polymer-membrane fuel cells and their direct conversion of chemical energy into electrical and thermal energy. This fuel cell energy training system operates in combined heat and power generation mode with hydrogen supply from a pressure vessel and oxygen from ambient air, controlled via integrated electronic load regulation.
Product Overview
The RVX 123 fuel cell energy training system enables students to study energy conversion principles, fuel cell design, and operating parameter relationships in a hands-on laboratory setting. The apparatus features a polymer-membrane fuel cell with nominal 100W output operating at 8.3A and 12V, capable of simultaneous electrical and thermal power generation. Hydrogen is supplied via standard pressure vessel with integrated high-pressure reducing valve, while oxygen draws directly from ambient air. An integrated electronic load allows precise adjustment of all operating points with accurate characteristic recording. Moisture regulation occurs automatically through operating temperature and air flow control without requiring external humidification. A comprehensive sensor suite monitors flow rate, pressure, temperature, voltage, and current strength. All measured values are recorded for fuel cell energy balance calculation, with optional transmission to PC via DAQ system and LABVIEW software.
