Description
The V&F PEMSense is an electron impact mass spectrometer (EI-MS) for the rapid measurement of H2, N2, O2, H2O and CO2 on PEM fuel cells.
The analyzer has a dual sample gas inlet: the anode side with a gas flow below 60 ml/min, and the cathode or exhaust side with a gas flow below 3000 ml/min.
Typical applications
- Fuel cell testing
- Fuel cell development
Application examples
Automotive industry
- Gas analysis in fuel cells
Measurable compounds
- Permanent gases: H2, O2, N2, CO, CO2
- Moisture: H2O
- Noble gases: Ar
- Hydrocarbons: CH4
Values marked as application-dependent (measuring range, response time, detection limit, gas consumption) depend on the compounds measured, the system configuration and the instrument settings.
