      Aerogel Composite, LLC has patented the nanotechnology for the preparation
      of aerogel composites for a wide variety of applications. Our flagship
      product is a carbon aerogel supported platinum nanocomposite for use as an
      electrocatalyst in polymer electrolyte membrane fuel cells (PEMFCs).

      Aerogel Composite, LLC, an R&D company established in May 1999, is located
      at the Connecticut Global Fuel Cell Center.

      Aerogel Composite, LLC's primary objective is to develop and supply aerogel
      based composite materials for a wide variety of industries. Aerogel
      Composite has developed a carbon aerogel based electrocatalyst for use in
      the manufacturing of fuel cell electrodes. The catalyst can reduce the
      platinum requirements for fuel cell vehicles to approximately 30% of current
      levels while improving performance.

      Aerogels are porous materials that are produced by sol-gel polycondensation
      reactions. The aerogel chemical composition, nanostructure, and physical
      properties can be controlled at the nanometer scale. Incorporation of
      additives into aerogels results in materials that are called aerogel
      composites. The role of additives is to enhance the properties of pure
      aerogels or to impart additional desirable properties depending on the
      application.

      Use as Electrocatalyst for Fuel Cells : A polymer electrolyte membrane fuel
      cell (PEMFC) is an electrochemical device that produces electricity, heat
      and water by combining hydrogen and oxygen gas. The PEMFC is being developed
      aggressively for use in on-site power generation and for the replacement of
      the internal combustion engine in vehicle applications. The PEMFC is
      comprised of a membrane electrode assembly (MEA) typically made of an
      ionically conducting polymeric membrane sandwiched between two
      electronically conducting electrodes. Typical electrodes for PEMFC
      applications are made of a gas diffusion layer (usually porous carbon paper)
      supporting a layer of finely dispersed platinum on carbon catalyst.

      Use as Catalysts : A catalyst is a substance that promotes a chemical
      reaction without becoming permanently involved in the reaction. Supported
      precious metal catalysts are used to catalyze a wide variety of reactions.
      Supports are generally high surface area materials such as alumina, silica
      and carbon. The activity and selectivity for a particular reaction depend in
      a complicated manner on a wide variety of factors including the average pore
      size and pore size distribution, the dispersion of the metal and
      metal-support interactions. Precious metal aerogel nanocomposites are
      alternatives to supported precious metal catalysts. Unlike conventional
      catalysts, their properties can be tailored at the nanometerscale to
      maximize activity and selectivity for a particular reaction.

      Aerogels are porous materials that are produced by sol-gel polycondensation
      reactions. A common feature of all aerogels is their small inter-connected
      pores. The aerogel chemical composition, nanostructure and physical
      properties can be controlled at the nanometer scale due to sol-gel
      processing.

      There are three major types of aerogels: inorganic, organic and carbon
      aerogels. Inorganic aerogels are obtained by supercritical drying of highly
      cross-linked and transparent hydrogels synthesized by polycondensation of
      metal alkoxides. Silica aerogels are the most well known inorganic aerogels.
      Organic aerogels are synthesized by supercritical drying of the gels
      obtained by the sol-gel polycondensation reaction of resorcinol with
      formaldehyde in aqueous solutions. Carbon aerogels are prepared by
      pyrolyzing such organic aerogels in an inert atmosphere.

      Incorporation of additives into aerogels results in materials that are
      called aerogel composites. The role of the additives is to enhance the
      properties of pure aerogels or to impart additional desirable properties
      depending on the application.

      Aerogel Composite, LLC has patented the nanotechnology for the preparation
      of aerogel composites for a wide variety of applications. Our flagship
      product is a platinum loaded carbon aerogel nanocomposite for use as an
      electrocatalyst in polymer electrolyte membrane fuel cells. Below is a
      graphic depicting the process of aerogel formation using sol-gel technology.
