Articles of clothing and personal gear with on-demand power supply for electrical devices

An apparatus for a living organism, the apparatus with on-demand power supply for an electrical device, comprising:

• a. an article of personal gear;
• b. two or more stiff planar fuel cell devices, distributed in a plane, that removably couple to the article of personal gear to heat a body region of the organism and deliver electrical power to one or more electrical devices, wherein each of said planar fuel cells devices is an electro-chemical device;
• and
• c. at least one flexible interconnection for interconnecting said two or more stiff planar fuel cell devices, said flexible interconnection allowing said stiff planar fuel cell devices to move with respect to each other out of said plane, and said flexible interconnection having integrated therein or therewith electrical connections and fuel connections for each of stiff planar fuel cell devices;
• wherein the fuel cell devices are removably coupled to the article of personal gear by fitting into a pocket disposed on the interior surface of the article of personal gear, and wherein the fuel cell devices are polymer electrolyte membrane fuel cells.

An article of clothing with on-demand power supply for an electrical device, comprising:

• a. two or more stiff planar fuel cell devices, distributed in a plane, that deliver electrical power to one or more electrical devices, wherein a broad face of each of the planar fuel cell devices is substantially aligned in the plane;
• and
• b. at least one flexible interconnection for interconnecting said two or more stiff planar fuel cell devices, said flexible interconnection allowing said stiff planar fuel cell devices to move with respect to each other out of said plane, and said flexible interconnection having integrated therein or therewith electrical connections and fuel connections for each of stiff planar fuel cell devices;
• wherein the planar fuel cell devices integrate into the article of clothing by reversibly enclosing the fuel cell devices into a pocket located on the interior of an upper rear torso-covering region of the article of clothing, and wherein the fuel cell devices are polymer electrolyte membrane fuel cells.
