DIFF Subgroup
H01M 8/0258 characterised by the configuration of channels, e.g. by the flow field of the reactant or coolant
Introduced: January 2016
Full Title
Full titles differ between systems:
IPC:
Fuel cells; Manufacture thereof > Details > Collectors; Separators, e.g. bipolar separators; Interconnectors > characterised by the configuration of channels, e.g. by the flow field of the reactant or coolant
CPC:
Fuel cells; Manufacture thereof > Details (electrodes H01M4/86 - H01M4/98) > Collectors; Separators, e.g. bipolar separators; Interconnectors > characterised by the configuration of channels, e.g. by the flow field of the reactant or coolant
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
IPC defines codes here since 2016.
