DIFF Subgroup
H01M 8/1018 Polymeric electrolyte materials
Introduced: January 2016
Full Title
Full titles differ between systems:
IPC:
Fuel cells; Manufacture thereof > Fuel cells with solid electrolytes > characterised by the electrolyte material > Polymeric electrolyte materials
CPC:
Fuel cells; Manufacture thereof > Fuel cells with solid electrolytes > characterised by the electrolyte material (H01M8/12 takes precedence) > Polymeric electrolyte materials
IPC and CPC are identically structured here. All 7 subcodes exist in both systems.
IPC defines codes here since 2016.
