Solid Oxide Fuel Cells with Improved Bipolar Plate Supported Fuel Cell having a Sealed Anode Compartment & Method of SealingIntellectual Property Available to License
A bipolar plate supported solid oxide fuel cell with a sealed anode compartment is provided. The solid oxide fuel cell includes a cathode, an electrolyte, and an anode, which are supported on a metallic bipolar plate assembly including gas flow fields and the gas impermeable bipolar plate. The electrolyte and anode are sealed into an anode compartment with a metal perimeter seal. An improved method of sealing is provided by extending the metal seal around the entire perimeter of the cell between an electrolyte and the bipolar plate to form the anode compartment. During a single-step high temperature sintering process the metal seal bonds to the edges of the electrolyte and anode layers, the metal foam flow field and the bipolar plate to form a gastight containment.
Increased performance and stabilityIntellectual Property Available to License
Scientists at Argonne National Laboratory have developed a method for creating a new class of platinum multi-metallic catalysts that are not only compositionally stable but also exhibit an advantageous electronic structure with enhanced catalytic properties.
Using this process, researchers created an alloy of platinum and one or more transition metals (such as cobalt, nickel, iron, titanium, chromium and others). Next, they modified the near surface layers by annealing, which induces formations known as nanosegregated surfaces. These surfaces vastly improve performance by overcoming kinetic limitations for the oxygen reduction reaction. The result is a catalyst particularly advantageous for use in polymer electrolyte fuel cells.
In the energy industry, fuel cells are rapidly becoming an important component. However, the high cost of manufacturing the platinum catalyst—a required element in a fuel cell—makes fuel cells relatively non-competitive in the commercial world. So far, such catalysts have not been able to demonstrate the performance and life expectancy consistent with a fuel cell’s long-term operation. Argonne’s invention overcomes this limitation.

Versatile simulation software package that allows the user to design, analyze, and compare different fuel cell configurationsIntellectual Property Available to License
Argonne’s GCTool (General Computational toolkit) is a versatile simulation software package that allows the user to design, analyze, and compare different fuel cell configurations, including automotive, space-based, and stationary systems.
GCTool uses a modular approach to integrate many of the detailed thermodynamic and component models developed during decades of fuel cell and power system research. It’s flexible and easy-to-use, allowing researchers to modify all the system inputs such as fuel, feed rates, and component performance.
GCtool provides a convenient, flexible framework for integrating various component models, in C or any C-linkable language, into simple or complex system configurations. A library of models for subcomponents and property tables common to many different systems and powertrains are available, and users can easily add their own models as needed.
Currently, more than 50 organizations use GCtool for systems analysis and evaluation, including private-sector fuel cell companies and universities.
