New Type

The possibility of using base metals and alloys based on them as electrodes for a new type of membraneless fuel cells operating on renewable fuel has been investigated. The phase boundary of two immiscible liquids in the ethanol-water-potassium hydroxide system plays a role of a membrane in these elements. Top phase of this fuel cell has significant alcohol content and insignificant electrolyte content, bottom phase has significant electrolyte content and insignificant alcohol content. Platinum- and ruthenium-coated titanium electrode, carbon electrode and stainless steel electrode were used as the anode. Stainless steel electrode and carbon steel electrode were used as the cathode. The possibility of using ferrous alloys as anode and cathode catalysts in this type of fuel cells is shown.

Membraneless Fuel Cells

Systems of two immiscible liquids are proposed for a new type of membraneless fuel cells using renewable fuel, in which the stationary phase boundary carries out a role of membrane. These systems consist of water, alcohol (preferable ethanol) and a number of electrolytes (salts and bases) leading to the layering of aqueous alcohol. In such systems top phase has significant alcohol content and insignificant electrolyte content, bottom phase has significant electrolyte content and insignificant alcohol content. To study the layering conditions in these systems, binodal curves were plotted for three two-phase liquid systems (EtOH + K2CO3 + H2O; EtOH + K3PO4 + H2O, EtOH + KOH + H2O), using the cloud point method. Comparison of our experimental data with the results of other authors showed that they are consistent for the first and second systems, and the temperature dependence of the binodal curves is clearly visible for the third system. The specific system EtOH – 30 % m/m; KOH – 40 % m/m; H2O – 30 % m/m was taken as the basis for studies of fuel cells based on two immiscible liquids. A further area of research lies in the field of optimizing the composition of both phases, studying the processes of mass transfer in these systems and their physicochemical characteristics.

New Type

A new type of martensite stainless steel deposit electrodes was developed. The welding technicality of the electrodes was analyzed, and the wear resistance of the deposited metal was studied through a slurry abrasive wear test. The results indicated that the welding arc of the electrodes could keep steady during welding process, and the appearance of weld and the detachability were satisfied. The microstructure of the hardfacing alloy consisted of lath martensite and fine strengthening phase with dispersive distribution. The mass loss of hardfacing alloy was about one third of that of substrate, which means the hardfacing alloy has a good wear resistance property. And the main wear mechanisms are micro-cutting, micro-ploughing and the second wear of plastic deformed metals.

Industry Wastewater

Recent research have found out that Bio Electrochemical Systems (BES) are proving to be efficient in both power generation and in waste disposal. The best example for a BES is a microbial fuel cell. The microbial fuel cell (MFC) uses the organic and the inorganic materials in the wastewater to produce electricity by the action of the microbes on them. Thus the MFC’s can be used for both bio-electricity generation and wastewater treatment. The power generation and the efficiency of the MFC depends on various factors like the type of bacteria, type of electrode used and organic content in the effluent. Experiments were carried out to treat textile industry wastewater using Microbial Fuel Cell. Graphite was used as anode, stainless steel and aluminium mesh were used as cathode. Influence of cathodes on power production and COD reduction on process has been critically examined. The maximum power density and COD reduction were observed in graphite and stainless steel electrode system

Ohmic Resistance

In this research, electrochemical impedance spectroscopy is employed to monitor the resistance of a fuel cell during operation with different operating conditions and different materials for the bipolar plates. The operating condition variables are cell humidity, pure oxygen or air as oxidizer, and current density. Three groups of single cells were tested: a graphite cell, a stainless steel cell (treated and original), and a thin, small, treated stainless steel cell. A treated cell here means using an electrochemical treatment to improve bipolar plate anticorrosion capability. From the results, the ohmic resistance of a fully humidified treated stainless steel fuel cell is 0.28 Ω cm2. Under the same operating conditions, the ohmic resistance of the graphite and the original fuel cell are each 0.1 Ω cm2 and that of the small treated cell is 0.3 Ω cm2. Cell humidity has a greater influence on resistance than does the choice of oxidizer; furthermore, resistance variation due to humidity effects is more serious with air support. From the above results, fuel cells fundamental phenomenon such as ohmic resistance, charge transfer resistance, and mass transport resistance under different operating conditions could be evaluated.
