The use of glucose, which is produced from the acid hydrolysis of starch and cellulose, is studied as a fuel in a low-temperature direct-mode fuel cell (LTDMFC) with an alkaline electrolyte. Glucose is regarded as being as good a fuel as bioethanol, because both the fuels give 2 electrons per molecule in the fuel cell without carbonisation problems. However, glucose can be produced with fewer proc...<br/><br/>Spets J-P, Kuosa M, Granström T, Kiros Y, Rantanen J, Lampinen M J, Saari K (2010) <i>Materials Science Forum</i> 638-642: 1164-1169<br/>

This paper deals with the kind of the bioorganic fuel cells that are equipped with or without ion exchange membranes. The bioorganic materials of interest are alcohols (methanol, ethanol) and glucose, which are obtained from renewable energy sources such as biomass. The operation temperatures of the direct fuel cells cover from room temperature up to 150 °C. The direct bioorganic fuel cells belon...<br/><br/>M J Lampinen, Y Kiros, J-P Spets, T Anttila (2010) <i>International Journal of Hydrogen Energy</i> 35: 22 12635-12641<br/>

In this study a test of the direct-mode bioorganic fuel cell (DMBFC) in which the fuel and the alkaline electrolyte are mixed with each other at two temperatures of 20 and 35 oC are carried out. The direct-mode bioorganic fuel cell is exposed to an externally generated electromagnetic field with simultaneous discharging in order to split the fuel molecule before the electrochemical oxidation at th...<br/><br/>J.-P.

In this study a direct-mode fuel cell in which the fuel and electrolyte are mixed with each other is tested. An alkaline electrolyte is used. The aim was to develop a fuel cell which operates directly by mixing the fuel with the electrolyte. The target is to create a fuel cell with a capacity of a few mW cm−2 with starch as a fuel source. Starch, glucose, and sorbitol were tested as fuels for ...<br/><br/>J-P Spets,Y Kiros, M Kuosa, J Rantanen, M J Lampinen, K Saari (2010) <i>Electrochimica Acta</i> 55: 26 7706-7709<br/>

In this study a direct-mode fuel cell in which the fuel and electrolyte are mixed with each other is tested. An alkaline electrolyte is used. The direct-mode fuel cell is exposed to an externally generated electromagnetic field between electrodes to cause both the splitting of the fuel molecule into smaller units (i.e. electrochemical reforming) and an increase in the activity of catalyst material...<br/><br/>J-P.Spets, M.

In the present study, a direct-mode glucose fuel cell with a neutral-state and near-neutral-state aqueous electrolytes is studied. The near-neutral state electrolytes are important for two reasons. Firstly, the pH of the electrolytes would be near the pH of liquid in living cells. Secondly, the neutral electrolyte would enable good corrosion resistance of catalyst materials. Three different cataly...<br/><br/>J.-P. Spets, Y. Kiros, T. Noponen, M.Kuosa, J. Rantanen, M.J. Lampinen, K. Saari (2009) <i>The Open Fuels & Energy Science Journal</i> 2: 82-86<br/>

This study deals with the R&D regarding the direct glucose fuel cell with a capacity of increasing the power density with glucose as a fuel. The direct-mode fuel cell in which the fuel and the alkaline electrolyte are mixed with each other is tested at room temperature.

This paper is a study about a direct mode fuel cell with a near-neutral-state and alkaline electrolytes. The aim of study was to develop a fuel cell, which operates directly by mixing the fuel with the electrolyte. This arrangement helps to avoid inserting membranes and additional bacterial cultures in fuel cell. The target is also to create a fuel cell with a capacity of few mWcm-2 with the starc...<br/><br/>J-P Spets, Y Kiros, M.

Organic emissions during the thermal drying process are strongly dependent on the drying temperature. In the traditional single stage drying system, the inlet temperature of the drying air has to be relatively high in order to keep the airflow for drying small. In the multistage drying system, the drying airflow is heated up again after the first drying stage with higher moisture content, and then...<br/><br/>J-P Spets, P Ahtila (2004) <i>Drying Technology </i> 22: 3 541 - 561 <br/>

The drying of moist biofuels such as wood-based biomasses should be as effluent-free and as energy-efficient as possible in order to ensure the safe and economical operation of industrial CHP plants. This work presents a multistage drying system (MSDS), which provides significant benefits in comparison with earlier conventional single dryer systems. This new application is installed most promising...<br/><br/>Spets J-P (2003) <br/>

In biofuel drying in industrial power plants, a new multistage drying system (MSDS) can now be applied before combustion. By reducing the drying air mass flow, MSDS makes it possible to use a proportion of the combustion air in drying, and to lead that moist drying air into the combustion stages of the power plant boiler. MSDS increases the power-to-heat ratio and capacity of the power plant compa...<br/><br/>J-P Spets, P Ahtila (2002) <i>Applied Thermal Engineering</i> 22: 10 1175-1180 <br/>
