“…The cost of the SOFC is attributed to the material, manufacturing process and operating condition. The SOFC also suffers from sulfur poisoning [81], corrosion issues [82], and coking [81,83], which further hinders its applications. The recent trend is to focus on developing a SOFC that can operate at low temperature and the introduction of new materials to improve performance, durability, reliability and cost.…”

Fuel cells and solar energy are promising candidates for electricity generation. It is forecast that fuel cells and solar power systems will play an important role in reducing the greenhouse gas footprint and replacing fossil fuels. Therefore, the limitations of fuel cells and solar power systems, such as low efficiency, high cost, and low reliability, must be addressed appropriately to enable their full potentials. Metal foam is a new class of material that has gained immense attention due to its excellent properties suitable for a wide range of applications. Its unique characteristics distinguish it from typical solid metals. The properties of metal foam can be modified during the fabrication stage by manipulating its physical structure. The goal of this paper is to review the application of metal foam in fuel cells and solar power systems. Besides, the performance of metal foam in fuel cells and solar systems is also discussed. Metal foam has been applied to the electrodes, gas diffusion layer and flow field of fuel cells to enhance performance, especially in regard to current density and flow distribution. Furthermore, metal foam is a heat exchanger for the solar energy harvesting system to improve its efficiency. Superior performances in experimental testing allows the possibility of commercialization of metal foam products in the renewable energy field.

“…The work was continued by Low et al in which the composition of copper/nickel was changed to 2.5 using electrochemical plating [81]. Observations of carbon deposition were the same as in the work discussed previously, but the effect of the composition of copper and nickel on the resistance was not discussed in both papers.…”

“…It was shown that the composite Cu/GDC coatings with up to 12 vol% of GDC in the coating had high electrical conductivity (5.27 and 1.46 × 10 5 S cm −1 at 20 °C and 600 °C, respectively)—comparable to that of Cu (5.96 and 1.76 × 10 5 S cm −1 ). The ELD procedure developed in [ 99 ], was further applied by the same group to surface modification of Ni foam with Cu to use it as a coking resistant current collector for syngas (CO+H 2 mixture, obtained by gasification of coal or steam reforming from natural gas)-fed SOFCs with a La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3− δ (LSCM) anode catalyst [ 100 , 101 ]. Deposition was performed at room temperature and with a current density of 10 A cm −2 .…”

Electrolytic deposition (ELD) and electrophoretic deposition (EPD) are relevant methods for creating functional layers of solid oxide fuel cells (SOFCs). This review discusses challenges, new findings and prospects for the implementation of these methods, with the main emphasis placed on the use of the ELD method. Topical issues concerning the formation of highly active SOFC electrodes using ELD, namely, the electrochemical introduction of metal cations into a porous electrode backbone, the formation of composite electrodes, and the electrochemical synthesis of perovskite-like electrode materials are considered. The review presents examples of the ELD formation of the composite electrodes based on porous platinum and silver, which retain high catalytic activity when used in the low-temperature range (400–650 °C). The features of the ELD/EPD co-deposition in the creation of nanostructured electrode layers comprising metal cations, ceramic nanoparticles, and carbon nanotubes, and the use of EPD to create oriented structures are also discussed. A separate subsection is devoted to the electrodeposition of CeO2-based film structures for barrier, protective and catalytic layers using cathodic and anodic ELD, as well as to the main research directions associated with the deposition of the SOFC electrolyte layers using the EPD method.

“…[4] Furthermore, it has also been shown that such surface carbon impurities can be removed efficiently via steam oxidation by catalytical coatings like CeO 2 . [4] As for the Cu-Ni systems, Cu-coated Ni foams might improve the energy density, the stability and the sulfur tolerance of SOFCs in the operating temperature range between 750 • C and 900 • C. [22,23] A higher electrical conductivity for Ni-Cu/YSZ systems (referenced to conventional Ni/YSZ systems) has been obtained by high-energy ball milling. [24] Further improvements could be achieved by combining bimetallic systems, CeO 2 and yttria-stabilized ZrO 2 .…”

Thin films of YSZ, unsupported Ni-Cu 1:1 alloy phases and YSZ-supported Ni-Cu 1:1 alloy solutions have been reproducibly prepared by magnetron sputter deposition on Si wafers and NaCl(001) single crystal facets at two selected substrate temperatures of 298 K and 873 K. Subsequently, the layer properties of the resulting sub-µm thick thin films as well as the tendency towards carbon deposition following treatment in pure methane at 1073 K has been tested comparatively. Well-crystallized structures of cubic YSZ, cubic NiCu and cubic NiCu/YSZ have been obtained following deposition at 873 K on both substrates. Carbon is deposited on all samples following the trend Ni-Cu (1 : 1) = Ni-Cu (1 : 1)/YSZ > pure YSZ, indicating that at least the 1 : 1 composition of layered Ni-Cu alloy phases is not able to suppress the carbon deposition completely, rendering it unfavorable for usage as anode component in sub-µm sized fuel cells. It is shown that surfaces with a high Cu/Ni ratio prohibit any carbon deposition, however.
