Separation of water (H2O) into hydrogen H2 and oxygen O2

With AIP H2 test benches, tests and characterizations are carried out on Fuel Cell Membrane Electrode Assemblys (H2 FC-MEA), Fuel Cell Stacks (H2 FC-STACK) or on Electrolyser Cells / Stacks (H2 EC Electrolyser) under defined and reproducible operating conditions.

 

  • The AIP H2 test benches are based on a modular system and are designed to be self-sufficient and flexible
  • In-House developed test bench automation system for all hydrogen test benches (AIP-MCS)
  • Production and software from one source

 

H2 EC-Electrolyseur

 

 

Features

  • Dynamic pressure control at cathode and anode
  • Gas volume flow measurement at anode and cathode (H2 and O2)
  • Measurement of dewpoint, pressure, and temperature after the cell
  • Drying of the product gases H2 and O2 by tube bundle heat exchangers
  • Pressurized DI water supply with integrated ion exchanger
  • Electronic power supply (optional)
  • Automatic condensate separation with sampling option
  • Inerting in the event of a fault with nitrogen at cathode and anode
  • Plausibility and monitoring functions (H2 warning unit, flow monitoring exhaust air system, leak test, monitoring of customer media, ...)
  • Automated, unmanned operation
  • Modular DAQ system for data acquisition and data visualization
  • Possibility of connection to the customer’s ATEX exhaust air system
  • Cooling circuit for tempering the DUT (optional)
  • Impedance spectroscopy (EIS) to characterize the cells, including Cyclovoltammetry and linear sweep voltammetry (optional)
  • Cell voltage monitoring up to 800 channels (optional)

Application
