Analisi dei contaminanti per la qualità dell'idrogeno
Fabrizio Manassero - ETG Risorse e Tecnologia
L'intervento affronta le sfide tecniche e normative legate alla qualità dell'idrogeno e alle metodologie di misurazione accurate.
(in lingua inglese)
Application for Hydrogen Contminants Detection
ISO 14687 contaminants
Hydrogen Application (examples..)
Why measuring - PEM fuel cell
- Power generated
- H2+O2 react and form H2O
- Impurities like sulfurs CO et al. Quickly and irreversibly reduce the performance and lifetime of fuel cells
Hydrogen Quality requirements for PEM
- H2 purity >99.97%
- Many impurities with PPM and PPB limits
Technologies used for detection
FTIR analysis contaminants
Model Construction
Enhanced absorption spectroscopy
Optical cavities
Extended Pathlenght
Lambert beer Law
Laser developed in MIR
Strongest absorption
Laser Spectroscopy Advantages
H2 fuel cells required UHP Hydrogen as fuel
ISO 14687:2019 defines H2 quality specification for PEM fuel cells
ETG Risorse e Tecnologia offers a complete solution for ISO measurement
Depending on the manufacturing process, often a reduced measurement can be used
