A bipolar plate and a direct liquid feed fuel cell stack are provided. The bipolar plate includes a manifold that is coupled with the fuel/oxidant path holes and a plurality of flow channels that are coupled with the manifold. The flow channels are divided into a plurality of groups, where the flow channel of each group forms a serpentine flow path and a length of each flow channel is substantially the same.

Bipolar plate and direct liquid feed fuel cell stack

A bipolar plate for fuel cells includes a plurality of flow paths in which fuel flows. The flow paths include a first flow path formed by a plurality of flow channels and a second flow path formed by a plurality of islands. A direct liquid fuel cell stack comprises the bipolar plate.

The present invention provides a portable support device adapted for being disassembled into segments for packing and being readily assembled. The support device in a first embodiment has a base block to which a pair of arms is assembled and to which a segmented pole is mounted in vertical orientation to support a mosquito net. In a second embodiment, an arm is assembled to a beam to define a horizontal plane and a segmented pole is assembled to the beam in a vertical orientation without use of a connecting block. In third and fourth embodiments, a pair of horizontal members are connected to each other and to a vertical support pole by a rigid connector. According to a third embodiment, a junction piece having two studs extending in a horizontal plane and a third stud in vertical orientation with an arm mounted to each of the horizontal studs and a pole mounted to the vertical stud to form a support apparatus. In a fourth embodiment, a first horizontal arm is assembled by a perpendicular connector to a vertical pole and a second horizontal arm is assembled to the first horizontal arm, forming a base for support between a mattress and a surface.
