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
