Computer Controlled PEM Fuel Cell Advanced Unit (EC6C)
PL-344197
The “EC6C” Computer Controlled PEM Fuel Cell Advanced Unit, developed by EDIBON, is designed to provide students with a comprehensive understanding of proton exchange membrane (PEM) fuel cell technology. The unit enables the calculation of critical parameters such as power density, polarization curves, and efficiency, and it allows for the study of how these parameters change depending on reagent consumption and power output.
The unit comes with a stack of 72 PEM cells, rated at 1000 W. These cells are designed with a channeled plate shape that facilitates the flow of air and hydrogen through the membrane, which generates the release of electrons. The cells are self-humidifying and do not require external humidification. The integrated fan ensures that the stack operates at the proper temperature by supplying the necessary airflow.
Hydrogen storage is a critical component of this system. The unit includes two pressure regulators: one for regulating the outlet pressure of the hydrogen bottle (5 – 50 bar) and another to control the inlet pressure to the stack (0 – 1 bar) from the metal hydride bottle. To manage hydrogen flow, the unit features two solenoid valves: one for controlling the hydrogen inlet before the stack and the other at the outlet to purge excess water and hydrogen to ensure proper operation.
For studying electrical energy generation, the unit includes a load regulation system, allowing for the generation of characteristic operational curves, which can be compared with theoretical data. The entire electrical circuit is safeguarded by a short-circuit unit to protect against overcurrent (30 A) and low voltage shutdown (36 V). Additionally, a hydrogen leak detector is included, with a detection range from 0 – 2% Vol and 0 – 100% L.E.L. (Lower Explosive Limit).
The unit is fully integrated with EDIBON's SCADA-based Computer Control System. It features a Control Interface Box, a Data Acquisition Board, and specialized software for process control, data acquisition, and real-time parameter management, providing complete control and analysis of fuel cell operation.
