Fuel Cell Applications

Challenges

Challenges for H2 measurement in electrolyzers:

  • Humidity in the process gas falsifies measurements with thermal conductivity
  • Cross-sensitivity compensation or dehumidification of the gas is required
  • The reaction times (t90) should be kept low in the process require complex sample preparation
  • Some processes receive corrosive gases
  • High operating pressures and process temperature require additional sample preparation

Advantages Archigas devices

Advantages of the TCD3000 for H2 measurement in electrolysers:

  • Humidity-independent measurement with thermal conductivity.
  • Short response times of less than one second.
  • Pressures up to 200 bara are permissible.
  • Corrosion resistance.
  • Continuous online quality monitoring up to H2 5.0 possible.
  • Process gas temperatures up to 100°C possible.
  • No additional costly equipment needed for quality measurement.
  • Reasonable price.

DESCRIPTION

MCA 100 SYN series of gas analyzers are the ideal solution for biogas measurement and industrial combustion applications because of their accuracy, stability, reliability, broad measurement range, and the variety of available form factors.

Unlike other analyzers, MCA 100 non-dispersive infrared (NDIR) gas analyzers measure multiple gases in an instrument with a single optical path platform.

Single-gas analyzers are inadequate when using methane as a biofuel because the gas often contains large amounts of CO as a contaminant. The analyzers can measure CO2, CO, and O2 in addition to methane and therefore provide the optimal combination of gases for combustion optimization.

The enhanced optics and electronics of our NDIR analyzers have virtually eliminated zero drift after the initial warm up period. The temperature and pressure compensation eliminates the major causes of span drift in many NDIR instruments.
