Abstract
The new photoelectric method of the detection of hydrogen is proposed, based on strong dependence of the photo induced current on concentration of hydrogen in III-V heterostructures with Pd contact. The given influence at a room temperature is stronger on few orders than influence of hydrogen on electric characteristics of solid-state elements in existing sensors. The original design of portable sensor module was developed on the base of photosensitive element and infrared light-emitting diode that meet demands of hydrogen power engineering.
