| Summary: | A fuel cell can be best defined as an electrochemical
converter of fuel and oxidant of chemical energy to
electrical energy. The important components of
micro fuel cells are the electrodes and catalysts
because the kinetics and rates of the electrochemical
reactions depend on their materials. All fuel cells
consist of two electrodes: the anode, where fuel oxidation takes place, and the cathode, which is used to
reduce the oxidants. The present review article
highlights the use of a range of electrodes made up
of different materials, a variety of catalysts that have
been used in previous studies, and their fabrication
materials and approaches. In this article, electrodes
and catalysts are classified into two types based on
the design approach applied to produce the micro
fuel cell: micro fuel cell design and conventional
assembly design. Most previous studies on fuel cells
have demonstrated that the construction and position of the electrodes play crucial roles in improving
the performance of micro fuel cells.
