Abstract
An article of clothing with an on-demand power supply for electrical devices is provided. The power supply includes stiff planar fuel cell devices that are distributed in a plane. The number of fuel cells is dependent on the power requirements for the electrical devices. The planar stiff fuel cells are flexibly interconnected in the plane by a flexible interconnection, which allows the fuel cells to move with respect to each other out of the plane. This further allows the power supply to be nicely integrated in an article of clothing and minimizes negative impact to a body region or to the article of clothing. The electrical and fuel connections between the fuel cells are integrated with the flexible interconnection. To further integrate and increase ease of operation a control system is included to control the on-demand power supply or control power levels for the electrical device.
