The phrase "air cathode" is correct and usable in written English.
It can be used in contexts related to electrochemistry, fuel cells, or battery technology, where it refers to a type of electrode that facilitates reactions with oxygen from the air.
Example: "The design of the fuel cell incorporates an air cathode to enhance its efficiency and performance."
Alternatives: "oxygen cathode" or "atmospheric cathode".
Thus, we succeed in advancing the air cathode catalysts for both primary and rechargeable Zn-air batteries.

A single-chamber microbial fuel cell (MFC) is an MFC with an air cathode that is exposed to air on one side and water on the other side.
The cathodic biofilm in an air-cathode single-chamber MFC can utilize organic carbon sources whereas the cathodic biofilm in a two-chamber air-diffusion MFC was fed with an inorganic carbon source, such as NaHCO3.
Moreover, the cathodic biofilm in a Pt-loaded air-cathode was observed to be capable of removing nitrogen, with enhanced removal efficiency due to the pre-accumulation of nitrifying biofilm [ 13].
It was discovered that the formation of biofilm on the Pt-loaded air-cathode could decrease the power output due to the increased cathodic resistance and limited proton transfer rate [ 11]; however, recent research demonstrated that the biofilm formation on a bare air-cathode could enhance the electric power output from air-cathode MFCs [ 12].
Terracotta pots were converted into simple, single chamber, air-cathode bio-batteries.
This paper presents a computational model of a single chamber, air-cathode MFC.
