Since 2005, Lentatek has been carrying out activities in the field of hydrogen and fuel cell technologies. Along with involving in several national and international projects, we have been collaborating with the most reputable universities in our country.
Experience we have acquired over the years has allowed us to publish national and international research on membrane preparation/production for Proton Exchange Membrane Fuel Cell (PEMFC) and Solid Oxide Fuel Cell (SOFC), single cell and stack design, preparation of fuel for fuel cell and production of hydrogen from sodium boron hydride (SBH), and to bring in many new patents and utility models.
We have been carrying out R&D activities with Niğde Ömer Halisdemir University within the framework of university-industry cooperation through our staff and laboratory located in the same university’s Nejat Veziroğlu Clean Energy Application and Research Centre along with our clean energies R&D laboratory in Incek, Ankara.
CAPABILITIES
Proton Exchange Membrane Fuel Cell (PEMFC)
Membrane Electrode Assembly (MEA) is composed of ion exchange membrane, catalyst layer, gas diffusion layer and sub-gasket. These MEA’s could made of 3/5/7 layers according to customer’s request.
PEM Stack & System
For civil and military purposes, 1-50 kW open cathode and dead-end PEMFC stacks and systems with liquid or air cooling, and with metallic or composite graphite bipolar plates are being developed.
Solid Oxide Fuel Cell (SOFC)
ScSZ and YSZ based electrolyte supported and NiO based anode supported MEAs are produced.
SOFC Stack
For civil and military purposes, 1-1.3 kW SOFC stack is produced.
Fuel Preparation
Catalysts
Catalysts, which are developed for hydrogen-rich gas production, are used for water/air reforming reactions with hydrocarbons such as diesel, LPG, natural gas and methanol.
Reformers
Steam reformers and desulphurisation reactors were developed to produce hydrogen-rich gas from liquid and gas fuels (natural gas, LPG, diesel, methanol, etc.).
Integration
Power and heat generating system integration can be achieved by stack, reformer, sulphur removalbalance of plant (BOP) and control unit components.
Sodium Boron Hydride (SBH) Synthesis
According to Schlesinger and Bayer method, one stage SBH synthesis can be achieved at laboratory scale in order to produce hydrogen.
Sodium Boron Hydride (SBH) Cartridge
As a hydrogen source, sodium boron hydride (SBH) cartridges at various energy values has been developed and especially PEM fuel cells integration was achieved for emergency power supply systems.
