Project summary

The goal of the project is the development of polymer electrolyte membrane fuel cell PEMFC {with solid polymer electrolyte (SPE)} with the efficiency up to 70%. Fuel cell is operating using direct conversion of chemical energy of the fuel (hydrogen, hydrogen containing gases) by its oxidation with oxygen or air with production of electrical energy. The only product is water.

Development of the fuel cell in accordance to this project will permit:


- to increase the efficiency of fuel conversion
- to develop ecologically friendly energy supply system for transport means, including city cars and buses; emergency energy supply systems (including systems for nuclear power stations); energy supply of remote objects (geophysical and meteorological stations etc.) with renewable energy sources.
- to solve ecological problems of Moscow and other large cities.

So the purpose of the project is connected with ecology and energy production and correlates with the purposes of ISTC.

The scientific significance of the project is: development of theoretical model of gas-diffusion electrode based on catalytic particle dispersion and SPE; development of synthesis of amorphous catalysts, including catalysts not sensitive to CO, using magnetron-ionic sputtering and ion implantation; investigation of the influence of structure and composition on catalytic properties; investigation of plasma chemical treatment of the membrane surface to improve membrane catalyst contact and to increase productivity and decrease platinum metal consumption. All these problems are important for electrocatalysis, plasmachemistry and other fields of science.

The practical significance of the project is: the increase of fuel utilization efficiency, development of ecologically friendly energy supply systems, reduction of the fuel cell price due to reduction of platinum metal amount, increase of the life time, productivity and improvement of the structure. Development of commercially available version of the fuel cell.

The results of the project will be the development of the theoretical model of fuel cell catalytic layer, receiving of data on kinetics and mechanism of the processes in the fuel cell, development of technology of catalyst synthesis and plasmachemical membrane surface treatment, optimization of fuel cell structure and decrease of it's price, development of pilot fuel cell with power 10 kW and efficiency up to 70% which will be the base unit for 200 kW fuel cell energy system.

In this project collaboration with Sandia National Laboratories (USA) is planned in the field of catalytic properties improvement and fuel cell investigations.
