Introduced: July 1974
Title
Titles differ between systems:
IPC: operating at high temperature, e.g. with stabilised ZrO electrolyte
CPC: operating at high temperature, e.g. with stabilised ZrO2 electrolyte
Full Title
Full titles differ between systems:
IPC:
Fuel cells; Manufacture thereof > Fuel cells with solid electrolytes > operating at high temperature, e.g. with stabilised ZrO electrolyte
CPC:
Fuel cells; Manufacture thereof > Fuel cells with solid electrolytes > operating at high temperature, e.g. with stabilised ZrO2 electrolyte
Of 7 combined children, 5 exist in both systems.
2 codes are CPC-only extensions.
Note: 2 CPC extensions are marked as secondary classification only.
IPC defines codes here since 2016.
