The development of efficient power supply sources (PSS) has always been and
remains to be one of the most promising areas that ensure the energy stability of
any country. A wide range of PPSs also includes the fuel cells (FC) that are pegged
as the most ecologically safe and promising energy sources because the reactions in
them are reduced to the formation of water from the fuel, in particular, hydrogen and
oxygen [1–3]. A sticking point of FC is the electrode materials that act as catalytic
agents, and in the vast majority of cases, these are expensive materials related to the
platinum and silver family [4–6]. In addition to their high electrocatalytic activity,
such materials differ by their stability and chemical resistance when exposed to the
media of different mineralization and corrosiveness. Earlier researches [7–11] show
that transition metal-based alloys can be regarded as decent competitors to precious
metals.
Lately, the research dealing with the study of new types of fuel for FC such
as methanol, ethanol, formaldehyde, and hydrocarbons have found a wide application [12]. Liquid fuels such as low molecular alcohols have certain advantages in
comparison with pure hydrogen because these are easy to store and transport. Moreover, their energy capacity is comparable with the energy capacity of usual liquid
fuels (gasoline, kerosene, etc.), for example, it will be equal to 6 kW/kg for methanol.
The obtained research data show that different organic substances are reversibly
oxidized on platinum family metals at relatively low anode potentials, and the electrocatalytic oxidation mechanism and the products depend on the electrode material
[13]. Today, platinum is considered as one of the best catalysts of the electrooxidation
of monoatomic alcohols; nevertheless, much attention is paid to the development of
less expensive materials that can replace it [14]. The main requirements set to the
