Fuel cell is a device that directly converts the chemical energy of fuels into electricity and heat (for example – conversion of syngas into electricity). It can generate electricity continuously as long as fuel and air (oxygen) are supplied. In order to obtain a sufficient voltage for use, fuel cells shall be connected together in so-called stacks.

Direct current which generates a cell can be used both directly and converted into an alternating current with a given frequency through an inverter. Produced heat can be partially used in the system (preparation of fuel) or fully discharged, for example, for heating or water heating.

Fuel cells are the main unit of the system (generator), which also includes the fuel preparation unit, air (oxygen) supply unit, cooling unit and control unit. Alternating power supply to the consumer occurs via an inverter. Capacity of fuel cells generator during operation is easily adjustable with the rate of 1 MW per second.

Fuel cells are the most effective alternative to traditional energy, can reduce the consumption of conventional fuels and to use alternative fuels.

Principle of operation of fuel cells implies a number of advantages of thermal and electric energy fuel cells generators in comparison to the common types of heat generators:

  • High electrical efficiency even at low power and at partial loads
  • Overall efficiency reaches 90%
  • Absence of moving parts, and as a result – high reliability, low rates of physical deterioration and almost complete absence of noise (noise level is not higher than that of domestic air-conditioner running), low maintenance costs
  • Up to 50% fewer CO2 emissions compared to the existing thermal power plants and cars, no harmful emissions of NOx, SO2, CO
  • Selection of installed capacity due to the modular structure of the fuel cells generator, power line – from 1 W to 100 MW
  • Capacity of fuel cells generator during operation is easily adjustable with the rate of 1 MW / second

  • High quality of stabilized zirconium dioxide powders for the manufacture of anode and high conductivity electrolyte
  • Operating temperature of the cell is 600ºC
  • Electron beam method (EB-PVD) of electrolyte sputtering allows to obtain an electrolyte film with higher conductivity compared to conventional technologies
  • Highly conductive thin (~ 3 mm) electrolyte (1Ce10ScSZ) from domestic production powder with internal resistance of 0.6 ohm x cm2 (world analogues – 2.0 ohm x cm²). The internal resistance of electrolyte of fuel cell is indicative of the rate of oxygen ion transfer between the electrodes (from anode to cathode), which determines the speed of electrochemical reaction of fuel oxidation on anode – one of the main indicators of efficiency of the fuel cell
  • LSCF film cathode for low temperatures with the optimal coefficient of thermal expansion, manufactured through electron-beam deposition (EB-PVD)
  • For the necessary structuring of anode materials was developed technology for improving the mechanical and electrical characteristics of the anode redox cycle
  • Powders produced from Ukrainian raw materials under our technology, provide the highest conductivity at the operating temperatures of the cell (the data obtained in the laboratory of the University of St. Andrew, United Kingdom). This directly demonstrates the possibility of creating ceramic fuel cell with a higher efficiency which will operate at a temperature of 600°C or even 500°C. This means the possibility to use for the production fewer costly materials
  • Powder produced under our technology due to the stepwise densification during sintering (powder particles morphology feature), allows to obtain highly porous (about 20%) structures even at sintering temperatures of 1500°C. which indirectly indicates its temperature structural stability. Such indicators do not have the ceramic created on the basis of commercial analogs of Ukrainian powder, manufactured by DKKK (Japan) and Praxair (USA). Ukrainian powder with its properties is best suited for creating electrode structures of fuel cells

Direct conversion of chemical energy into electrical and thermal. Operating principle on example of a Solid Oxide Fuel Cells (SOFC), main components of which are – anode, cathode, and electrolyte:

1) Fuel is supplied to the anode in the form of combustible gas (hydrogen, hydrocarbon compounds), where the catalyst facilitates its dissociation into cations

2) Oxidant gas (oxygen, air) is supplied to the cathode

3) At the cathode oxygen reduction, reaction takes place while it is ionized. Oxygen ions are passed through the ceramic electrolyte to react with the fuel. Reaction occurs at the anode

4) At the anode, the oxidation of fuel takes place, with the participation of fuel cations and anions of oxygen. Reaction liberates electrons and thermal energy. Also, the reaction products are water steam (in case of using pure hydrogen) or water steam and carbon dioxide (in case of using hydrocarbon fuel)
