A method of fabrication produces one or more functional microparticles using a parallel pore working piece. In one embodiment, the method forms a particle that includes a segment for the oxidation of a biofuel (such as glucose) and the reduction of oxygen. The particle may be synthesized in a structure with defined and parallel, uniform, thin pores that completely penetrate the structure. Further, the functional microparticle may be configured to reside in a human or animal body or cell such that it may be self-contained fuel cell having an anode, a cathode, a separator membrane, and a magnetic component. In other embodiments, the functional microparticles may deliver energy or therapeutic materials in the body.

The present disclosure is directed to triblock copolymer based anion exchange membranes (AEMs) and methods for making same. The membranes are useful as separators in electrochemical devices, such as fuel cells, electrolyzers, water desalination systems, and redox flow batteries.

A separator for a fuel cell, includes: a metal plate; a first electro-conductive resin layer formed on a first surface side of the metal plate; a second electro-conductive resin layer formed on a second surface side of the metal plate opposite to the first surface side; and a flow channel in which the metal plate and the first and second electro-conductive resin layers have a wavy shape in cross section.

A storage module of distributed flow battery is provided. An electrochemical reaction is processed with the positive and negative electrolytes to produce and/or discharge direct current and further output the positive and negative electrolytes after the reaction. The module comprises two end plates; two frames disposed between the two end plates; two current collectors disposed between the two frames; two complex cast polar plates disposed between the two current collectors; two electrodes disposed between the two complex cast polar plates; a membrane disposed between the two electrodes; and three gaskets. Therein, two of the gaskets are set to sandwich and enclose one of the two complex cast polar plates; and the other one of the gaskets is set between the other one of the two complex cast polar plates and an adjacent one of the current collectors.

Methods and systems are provided for manufacturing a membrane separator for a redox flow battery. In one example, the membrane separator is fabricate by a calendering process. The membrane separator may be configured with a polymer network to provide selectivity for ion transport across the membrane separator. The membrane separator may be further adapted with an integrated spacer in contact with a negative electrolyte.

Provided are a method for producing a fuel cell separator, and a separator material that can prevent carbon in a carbon layer formed on the surface of a metal substrate from being detached during press forming, and thus can suppress failures in the press forming. The method is a method for producing a fuel cell separator having formed thereon gas flow channels through which fuel gas or oxidant gas to be supplied to a fuel cell stack flows, the method including preparing a plate-shaped separator material including a titanium substrate, a carbon layer covering the titanium substrate, and a resin layer covering the carbon layer; press-forming the prepared separator material into the shape of the separator such that the separator has the gas flow channels formed thereon; and removing the resin layer from the press-formed separator.
