H2 Hydrogen Fuel Cell Testing
Hydrogen Fuel Cells: Testing of the Membrane Electrode Assembly with FC-MEA
With the H2FC-MEA, tests and characterizations are carried out on individual fuel cells or cell stacks under defined operating conditions. The H2FC-MEA is designed to be self-sufficient and flexible and based on a modular system. The test sequences parameterized with a sequence editor run directly on a real-time computer, which guarantees the uninterrupted execution and recording of very long test sequences.
Hydrogen fuel cells: Testing of the Membrane Electrode Assembly
Features
- Gas dosing with mass flow controller (H2 / air / oxygen)
- Dynamic humidification of the gases with bubble column reactors with a dry bypass to achieve high dynamics
- Adjustable operating points on the cathode and anode in terms of dew point, pressure, temperature and flow rate
- In the event of a fault, inerting with nitrogen at the cathode and anode
- Plausibility and monitoring functions (H2-warning unit, flow-monitoring, exhaust system, leak check, monitoring of customer-side media …)
- Automated, unmanned operation
- Measurement protocol and data export
- Possibility of connection to the customer‘s ATEX exhaust air system
Applications
- Anode and cathode preparation
- Automatic filling of the bubble column reactors for unmanned operation
- Cooling circuit for tempering the fuel cell (Delta p, Delta T or T regulation)
- Impedance spectroscopy to characterize the cells
- Electronic load (sink) for simulating
