Method for indirectly determining a molecule concentration in a storage area of a household refrigerating appliance, as well as household refrigerating appliance

摘要

The invention relates to a method for determining a concentration of molecules in a storage area (8) for food of a household refrigerating appliance (1), wherein the storage area (8) with a PEM electrolysis cell (11) of the household refrigerating appliance (1) is connected, and the molecule concentration the PEM electrolysis cell (11) in the storage area (8) is changed, wherein in the electrolysis of water at least one electrical parameter of the PEM electrolysis cell (11) is determined and depending on this electrical parameter, the molecular concentration in the storage area (8) is determined. The invention also relates to a household refrigerator (1).
