Key takeaways
- Cathode: platinum-on-carbon for H₂ evolution.
- Anode: iridium oxide for O₂ evolution.
- Catalyst loading and uniformity determine lifespan.
Why coatings fail
Mineral contamination from the wrong water, repeated thermal cycling and improper shutdown sequences all degrade catalyst layers over time. Quality machines sequence shutdown to protect the electrodes.
Frequently asked questions
Professional machines often have replaceable stack cartridges. Consumer machines are typically factory-serviced.
