Abstract: A heater element includes: a honeycomb structure; a negative electrode; a positive electrode; and a functional material-containing layer. The honeycomb structure includes an outer peripheral wall and partition walls disposed on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from an inlet end face to an outlet end face to form a flow path, at least the partition walls being made of a material having a PTC property. The functional material-containing layer includes at least a dehumidifying material, the functional material-containing layer being provided on surfaces of the partition walls.

Abstract: A vehicle air conditioning system includes: an air conditioning duct for allowing air to flow therethrough; a first humidity control unit having at least one humidity control device including a moisture absorbing material-containing layer, wherein the first humidity control unit is disposed in the air conditioning duct; a second humidity control unit having at least one humidity control member containing a moisture absorbing material, the second humidity control unit being disposed in the air conditioning duct on a downstream side of the first humidity control unit; and a power source for applying a voltage to the humidity control device. The total amount of the moisture absorbing material in the second humidity control unit is 0.3 to 12 times the total amount of the moisture absorbing material in the first humidity control unit.
