Embodiment Construction

[0009] In another embodiment of the flow field plate according to the claimed invention, the planar body comprises a through hole extending from the first surface to the second surface. The flow and distribution are thereby further improved, and the mechanical resistance experienced by the gas is further reduced. In particular, flow is thereby permitted in all planar directions and in directions perpendicular thereto.

[0010] In yet another embodiment, the substantially flat body has a maximum thickness defined as the length of a line from one surface to the other, but less than 50% of the substantially flat body has the maximum thickness. At locations where the thickness is less than the maximum thickness, space for gas flow is available at the surface.

[0011] A flow field plate according to the invention may be formed from multiple parts. This allows formation of forms not achievable by existing techniques (eg etching) and by techniques such as 3D printing (assuming ext...

Abstract

The present invention relates to a flow field plate for a solid state compressor cell, comprising an essentially flat body, having two opposite surfaces and an edge, provided with a channel plan for gas distribution, that extends from multiple locations at a border of the field plate to multiple locations at the surface of the essentially flat body wherein the essentially flat body is provided with recesses at both sides, the recesses at each side comprising a first set of parallel lanes, crossing a second set of parallel lanes.

Description

technical field [0001] The present invention relates to flow field plates for solid state compressor batteries. The invention also relates to a solid state compressor, and a compressor cell for electrochemically compressing a working fluid comprising such plates. Furthermore, the invention relates to a method for manufacturing such a plate assembly. Background technique [0002] Whereas conventional mechanical compressors utilize mechanical means such as pistons or rotors to compress a fluid, solid-state compressors rely on the electrochemical transport of the fluid across a membrane using an ion transport mechanism. To compress a working fluid electrochemically, solid-state compressors typically include a compressor cell consisting of one or more stacked membrane electrode assemblies (also known as MEAs). The electrodes of the MEA are connected to a power source for maintaining a potential difference across the electrodes. This potential difference is necessary to move t...
