Introduced: January 2016

Full Title

Full titles differ between systems:

IPC:

Fuel cells; Manufacture thereof > Details > Collectors; Separators, e.g. bipolar separators; Interconnectors > Non-porous and characterised by the material

CPC:

Fuel cells; Manufacture thereof > Details (electrodes H01M4/86 - H01M4/98) > Collectors; Separators, e.g. bipolar separators; Interconnectors > Non-porous and characterised by the material

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 2016.
