Hypercat represents Breton's family of electrocatalysts for polymer electrolyte fuel cells. Breton supplies catalysts produced by means of a patented procedure in which the active sites are appropriate platinum alloys (supported on carbon nanostructure materials) with average particle size of between 5 and 10 nm.
Research and development of materials for electrochemical devices
Since 2010 the Breton Institute of Technology has been investing in research, development and industrialisation of new materials suitable for use in electrochemical devices such as lithium batteries and polymer electrolyte fuel cells.
The materials developed are mainly applied in 'energy conversion' devices, for the conversion of electrical energy into chemical energy and chemical energy into electrical energy, in particular electrolysers and hydrogen-fuelled fuel cells.
Additional R&D areas concern the areas of 'energy storage', such as energy storage devices and graphene production.
Advanced modern laboratory
As the heart of the activity, the laboratory offers all latest equipment including reactors, ovens, controlled assembly presses, and glove boxes for controlled atmosphere synthesis operations, together with modern electrochemical measuring equipment.
High level know-how
The BIT electrochemical division handles industrialisation of materials that offer higher performance and lower cost than alternatives on the market.
The competence of the team of chemists specialised in synthesis and materials and devices characterisation spans from organic chemistry to materials science and analytical electrochemistry.
The value of collaboration
BIT works with academic and industrial partners in order to assess and optimise real applications of the proposed solutions.

TiF is titanium oxide doped with fluorine atoms, produced in compliance with a Breton patent. The special function with fluorine makes the material a suitable additive for polymer electrolyte membranes in order to increase their proton conductive properties.
Polymer electrolyte membranes in the market are based on fluorinated polymers, which assure excellent chemical stability and conductive capacity.
The presence of inorganic fillers increases the performance of these materials: specifically TiF, having functionalisation with ionic fluorine, interacts optimally with the membrane fluorinated polymer, thereby enhancing the membrane's physical-mechanical and conductive properties./ 02Breton TiF
LiFT is a solid state lithium ion electrolyte based on suitably functionalised metal oxides. This material can be used as a separator in lithium ion solid state secondary batteries, with many advantages:
Replaces existing flammable organic solvent based liquid electrolytes;
- Allows use of the lithium based anode thus increasing the amount of energy stored in the batteries;
- LiFT is non-flammable in air and therefore easy to manage in normal conditions./ 03Breton LiFT
Hypergraph is a nanocomposite material based on nanoscale graphene and metal oxides obtained by means of a patented Breton process that allows intimate mixing of the materials such as to modify their structures and functions.
To date, Hypergraph allows the following activities:
Preparation of electronically conductive graphene based inks (stable also in aqueous solvent);
- Introduction of graphene in polymer matrices increasing the heat and electricity conductive characteristics thus obtaining conductive composite polymers;
- Preparation of electronically conductive coatings that inhibit corrosive phenomena and hence the formation of layers of oxide in the substrates./ 04Hypergraph
Hypergraph-EVO is a Hypergraph derived material with functions in the carbon structure originating from the synthesis process. In this product, the metal oxide support is removed electrically by means of a chemical process.
Hypergraph-EVO is particularly suitable for use as a carbon substrate in all materials that require a wide specific area and high electronic conductivity.
Applications are the same as those of Hypergraph./ 05Hypergraph-Evo
