Also disclosed is a fuel cell for generating energy from a liquid anode fuel comprising one or more hydrazide compounds.

Disclosed embodiments describe approaches for warming a portion of a human body. The warming is based on heated apparel (e.g., a heated glove) coupled to an electrical power supply through a heater controller. The heated apparel (e.g., a glove) can be fabricated using a narrow knit electronic textile. A heater can be constructed from the narrow knit electronic textile. The heater is coupled to the heated apparel (e.g., a glove) for warming a portion (e.g., a hand) of a human body, wherein heating by the heater is accomplished using electrical power from the electrical power supply. The heater is controlled by a heater controller which is interposed between the heater and the electrical power supply.

In various embodiments, a solid oxide fuel cell features a functional layer for reducing interfacial resistance between the cathode and the solid electrolyte.

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.
