Abstract
We present an integrated voltage sensor dedicated to fuel cells monitoring. This sensor is based on Giant Magneto Resistances (GMR) as sensitive elements coupled to a micron size integrated metallic line which creates a field on the GMR elements when a current flows in it. Complete module containing eight channels with the associated electronics have been developed and successfully tested on fuel cells for automotive. Magnetoresistance, magnetic sensors, fuel cells, automotive.
