Title:
電気化学セルと共に使用するためのフロー構造
Document Type and Number:
Japanese Patent JP6608277
Kind Code:
B2
Abstract:
The design and method of fabrication of a three-dimensional, porous flow structure for use in a high differential pressure electrochemical cell is described. The flow structure is formed by compacting a highly porous metallic substrate and laminating at least one micro-porous material layer onto the compacted substrate. The flow structure provides void volume greater than about 55% and yield strength greater than about 12,000 psi. In one embodiment, the flow structure comprises a porosity gradient towards the electrolyte membrane, which helps in redistributing mechanical load from the electrolyte membrane throughout the structural elements of the open, porous flow structure, while simultaneously maintaining sufficient fluid permeability and electrical conductivity through the flow structure.
