  Producing a tunneling-based hydrogen sensor (12) comprises forming a first (18) and a second (20) electrode at a distance from one another on an electrically insulating surface of a substrate (16) and applying a hydrogen sensing layer (22) on that surface. Either the forming or the application step includes bringing the hydrogen sensing layer (22) into contact with the first (18) and second (20) electrodes. The application of the hydrogen sensing layer (22) includes printing of a layer of functional ink onto the electrically insulating surface, the functional ink comprising a dispersion of nanosized platinum group metal particles in a solvent, and curing the layer of functional ink by heating it in such as way as to cause at least part of the platinum group metal particles to form conductive paths having tunneling gaps therein. The invention further relates to a hydrogen sensor so produced.
