    摘要： A fuel-cell assembly has a plurality of unit cells, each of the unit cells comprising an anode, an electrolyte, a cathode, and a current collector. The fuel-cell assembly has a plurality of electrical interconnection elements, at least one electrical interconnection element being connected respectively to each anode, to each cathode, and to each current collector of the unit cells. The unit cells are arranged in a stack and are mechanically supported by electrical interconnection elements such that each of the unit cells of the stack has at least one edge free to move relative to the electrical interconnection elements.

    摘要： A printhead has a substrate with a first surface, an opposite substantially parallel second surface, and an edge surface extending from the first surface to the second surface. The substrate further includes a fluid channel that extends from the edge surface inward away from the edge surface and through a recess in the first surface. The printhead further has a heating element disposed over the first surface, and a firing chamber disposed over the heating element. The fluid channel directs fluid to the firing chamber through the recess, where the fluid is heated by the heating element and ejected therefrom.

    摘要： A microfluidic device includes a microfluidic coupon and at least one fluid channel associated with the microfluidic coupon. The fluid channel is configured to control fluid flow from one portion of the coupon to another portion of the coupon. A quantity of reconfigurable valving material is disposed within the fluid channel, the valving material being thermally coupled to an optically activatable material operable to increase a temperature of the valving material when exposed to an optical beam to at least partially soften at least one component of the valving material to allow reconfiguration of the valving material to switch a flow state of the fluid channel.
