In my city there is a bus using a hydrogen fuel cell.
I noticed it produced interference in my bluetooth headset with noise reduction (I can hear the engine in my headset), i'm curious if it will interfer with plane sensors.
This is maybe an inverter. But definitely not the fuel cell itself. The fuel cell will produce pure DC current which won't interfere with anything. However, e.g. a DC/DC inverter that steps up the voltage might not be well shielded.
