A vaporizer device includes a fuel cell disposed with a device body and configured to receive a cartridge having a first compartment that holds a vaporizable material, a second compartment that holds a fuel, a heating element, and a wicking element that can draw the vaporizable material to the heating element to be vaporized. The vaporizer cartridge is configured for fluidically, thermally, and/or electrically coupling to a vaporizer device body. Various implementations of the vaporizer cartridge are described that include one or more features for a fuel cell within the cartridge.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, a cartridge can include a reservoir housing that includes a reservoir chamber configured to selectively hold a vaporizable material, and an atomizer in fluid communication with the reservoir chamber. The atomizer includes a substrate having an array of ordered pores configured to draw a predetermined volume of vaporizable material from the reservoir chamber at a predetermined rate, and at least one heating material configured to selectively heat the at least a portion of the vaporizable material drawn into the substrate to generate a vaporized material. Vaporizer devices are also provided.
