Abstract:
The global environmental concerns and the escalating demand for energy, coupled
with a steady progress in renewable energy technologies, are opening up new
opportunities for the utilization of renewable energy resources. In this context
Direct Alcohol Fuel Cells (DAFCs) represent a promising energy conversion
device for mobile and stationary applications. Among the key issues to be
addressed for their technological exploitation, the alcohol cross-over represents a
limiting factor since the alcohol can be directly oxidized on the cathode and shortcircuit
the cell. In parallel, the recent improvement of anion membranes makes the
development of alkaline DAFCs competitive with the acid ones.
In this work we present the preparation (electrodeposition and sol-gel) and
characterization of Pt free metal and metal oxides as possible cathode and anode
materials in alkaline DAFCs.
More specifically, the electrodeposition protocols include the Selective
Electrodesorption Based Atomic Layer Deposition (SEBALD) used to prepare new
bimetallic electrodes for fuel cells. This new method of Electrodeposition, recently
pointed out in Florence on the basis of ECALE method, allows to deposit under
morphological and compositional control those metals that cannot be deposited at
underpotential. In parallel, low-temperature sol-gel synthetic process are adopted to
produce tailored nanostructured mixed oxide disperse phase electrocatalysts, to be
used as cathode material in membrane-electrode-assemblies (MEA).
