Description

Advantages of implementation of power plants based on electrochemical reactions are successfully demonstrated in the USA and Japan. One of the msot promising types of fuel cells (FC) is a type of high temperature fuel cells. At present, thanks to the efforts of the leading countries that develop fuel cell technologies power plants on the basis of molten carbonate fuel cells (MCFC) and solid oxide fuel cells (SOFC) are really close to commercialization. One of the problems that are to be solved for practical implementation of MCFC and SOFC is a problem of corrosion of metal components of stacks that ... continued below

Description

Advantages of implementation of power plants based on electrochemical reactions are successfully demonstrated in the USA and Japan. One of the msot promising types of fuel cells (FC) is a type of high temperature fuel cells. At present, thanks to the efforts of the leading countries that develop fuel cell technologies power plants on the basis of molten carbonate fuel cells (MCFC) and solid oxide fuel cells (SOFC) are really close to commercialization. One of the problems that are to be solved for practical implementation of MCFC and SOFC is a problem of corrosion of metal components of stacks that are assembled of a number of fuel cells. One of the major components of MCFC and SOFC stacks is a bipolar separator plate (BSP) that performs several functions - it is separation of reactant gas flows sealing of the joints between fuel cells, and current collection from the surface of electrodes. The goal of Task 1 of the project is to develop new cost-effective nickel coatings for the Russian 20X23H18 steel for an MCFC bipolar separator plate using technological processes usually implemented to apply corrosion stable coatings onto the metal parts for products in the defense. There was planned the research on production of nickel coatings using different methods, first of all the galvanic one and the explosion cladding one. As a result of the works, 0.4 x 712 x 1296 mm plates coated with nickel on one side were to be made and passed to ANL. A line of 4 galvanic baths 600 liters was to be built for the galvanic coating applications. The goal of Task 2 of the project is the development of a new material of an MCFC bipolar separator plate with an upgraded corrosion stability, and development of a technology to produce cold roll sheets of this material the sizes of which will be 0.8 x 712x 1296 mm. As a result of these works, a pilot batch of the rolled material in sheets 0.8 x 712 x 1296 mm in size is to be made (in accordance with the norms and standards of the Russian metallurgical industry) and supplied to the partner for tests in a stack of fuel cells. A feasibility study on the cost of the Russian material for a BSP is to be done on Tasks 1, 2 in case the annual order makes up 400,000 sheets. The goal of Task 3 of the project is to research on possible implementation of cermet compositions on the basis of LiAlO{sub 2}, TiN, B{sub 4}C, ceramics with Ni and Ni-Mo binders. BaCeO{sub 3} conductive ceramics with metal binders of Ni, Ni-Cr etc. were also planned to be studied. As a result of these works, a pilot batch of samples is to be made and passed to FCE for tests. The goal of Task 4 of the Project is development of a new alloy or alloys with a ceramic coating that will have upgraded corrosion stability in operation within a SOFC. A new alloy was to be worked out by the way of modification of compositions of industrial alloys. Ceramic coatings are to be applied onto ferrite steel produced serially by iron and steel industry of Russia as sheet iron.
