Metal oxides are important functional materials with a wide range of applications, especially in the field electrocatalysis. However, quick and accurate assessment their real electroactive surface area (ECSA), which is paramount importance for evaluation performance, remains challenging task. Herein, we present relatively simple strategy an situ determination ECSA commonly used metal oxide catalysts, namely Ni-, Co-, Fe-, Pt-, Ir-based oxides. Similar to well-established practice...
Liquid Organic Hydrogen Carrier (LOHC) systems offer a very interesting option for hydrogen storage in the existing infrastructure common fuels. Technically most attractive is direct use of LOHC-bound low-temperature PEM fuel cell. Here, isopropanol/acetone LOHC system suggested to produce electricity from condensable liquid without CO2 emissions. A high-performance isopropanol cell using vaporizer and commercial test demonstrated. For first time backpressure used enhance performance. The...
We present the first combination of a bipolar interface fuel cell with commercial Fe–N/C catalyst as an alkaline cathode and PGM-based, acidic anode, both separated by proton exchange membrane (PEM).
Liquid Organic Hydrogen Carriers (LOHC) offer a promising solution for hydrogen storage in the existing infrastructure conventional fuels. Within this framework, isopropanol/acetone couple as light-LOHC system is used to generate electricity direct isopropanol fuel cell (DIFC). This work focuses on impact of catalyst loading, ionomer content and support performance DIFCs. We achieve rise from 95 mW cm-2 219 under air operation by increasing anode loading 0.5 mg 4 cm-2, which can be...
Water management is a very important issue in low temperature fuel cells such as proton exchange membrane (PEMFCs) or anion cells. Within bipolar interface cells, water inhibits an even more critical role. The earlier work on (BPIFCs), employing Fe-N/C the cathode side for oxygen reduction reaction (ORR) alkaline environment, demonstrated increased stability of catalyst compared to acidic environment conventional PEMFCs. However, BPIFCs, severe mass transport limitations (MTL) dramatically...
Direct alcohol fuel cells (DAFC) produce electricity from liquid fuels such as methanol, ethanol etc., where the is oxidized at anode and oxygen reduced on cathode side of cell. Operation attractive because exceptionally high volumetric energy density easy handling in comparison to pressurized hydrogen. [1] Especially direct methanol (DMFC) have been widely investigated portable power sources. However, even with these relatively simple fuels, reaction kinetics electro-oxidation are slow...
