2013 results about "Porous substrate" patented technology

A coating with pores and pinhole defects creates ways for corrosive fluids or aggressive chemicals to attack the substrate material and leads to structure failure. A porous surface may also be known as a porous substrate.

Porous Substrates for Implantation

A porous substrate or implant for implantation into a human or animal body constructed from a structural material and having one or more regions which when implanted are subjected to a relatively lower mechanical loading. The region(s) are constructed with lesser mechanical strength by having a lesser amount of structural material in said region(s) relative to other regions. This is achieved by controlling pore volume fraction in the regions. A spacer is adapted to define an open-cell pore network by taking a model of the required porous structure, and creating the spacer to represent the required porous structure using three-dimensional modelling. Material to form the substrate about the spacer in infiltrated the scaffold structure formed.

Fuel cell

A current collector includes a thin porous substrate and a hydrophilic material, where the hydrophilic material is provided to holes of the thin porous substrate or surfaces of skeleton elements of the porous substrate so that hydrophilic areas formed by the hydrophilic material successively pass through the thin porous substrate between both surfaces of the thin porous substrate. In the current collector, water is let out through the hydrophilic areas and does not stay on an interface between an electrode and the current collector so that reaction gas is not hampered and is supplied, unlike a conventional current collector. When the current collector is applied to a polymer electrolyte fuel cell, water is supplied with reliability through the hydrophilic areas to a polymer electrolyte membrane so that the polymer electrolyte membrane is effectively humidified. The current collector applied to a cathode achieves a profound effect because reaction product water tends to stay around a cathode of any types of fuel cells. The current collector also includes gas flow paths which are surrounded by particles of a hydrophobic material and pass through the thin porous substrate between both surfaces of the thin porous substrate. As a result, gas permeability of the current collector is maintained with reliability.
