“…Because of the simplicity of membraneless FCs, they can be used to generate power for biological sample analysis (Esquivel et al 2014), wearable electronics (Valdés-Ramirez et al 2014, Bandodkar et al 2015, and supercapacitors (Lu et al 2014). Moreover, this type of FCs has a wide range of applicability due to the fact that they can produce energy using various solutions such as methanol (Zhang et al 2019), glucose (Shitanda et al 2017, Gonzalez-Guerrero et al 2017, vanadium (Jung and Ahn 2020), human blood (Dector et al 2017), urea (Chino et al 2018), formic acid (Copenhaver et al 2015), hydrogen peroxide (Yang et al 2019, Ehteshami et al 2016, Yan et al 2018, etc. Within this variety of fuels, hydrogen peroxide (H2O2) is an attractive fuel because: I) it has a carbon-free structure, II) it can be obtained via using renewable energy sources such as solar energy (Yamada et al 2010), it can be used both the oxidant and the fuel at the same time in an FC (Yamazaki et al 2008).…”

A paper-based membraneless direct hydrogen peroxide fuel cell was developed and tested under different potassium hydroxide concentrations (1 to 7 mol lt -1 , stepping by 2), different hydrogen peroxide concentrations (1, 2, 3 mol lt -1 ) and different temperatures (20, 30, 40 o C). Moreover, the developed fuel cell was studied for stability under stopped and continuous flow conditions. From the experiments, it was found that the maximum power density of 6.79 mW cm -2 and the maximum open circuit voltage of 0.87 V at 40 o C were obtained when the anode solution consisted 2 mol lt -1 H2O2 and 5 mol lt -1 potassium hydroxide and cathode solution consisted 2 mol lt -1 sulfuric acid and 2 mol lt -1 hydrogen peroxide. It was found that if the reactants were supplied constantly into the fuel cell, a current density of 3.12 mA cm -2 was obtained. The developed fuel cell produced energy for 91 minutes when the reactant flow was stopped.

“…[28][29][30] For the application of fuel cells, porous electrodes are highly advantageous for enhancing power density as such a structure offers high specific surface area, enabling fuel solution flow through anode to facilitate the electrochemical reaction. [31,32] For example, the peak power density of a microfluidic direct alcohol fuel cells fed by ethylene glycol increased from 1.6 mW cm −2 in a cell designed with flow over electrodes [33] to 20 mW cm −2 by using flow-through porous electrode configuration. [32] Hence, here, we propose to use polymerized high internal phase emulsions (polyHIPEs) for designing porous polymer substrates.…”

Such future soft wearable electronics or wearable 2.0 products [8] will not be viable unless efficient reliable and skin-conformal power sources are to be developed. Most of the current wearable electronics are powered by rigid and bulky lithium-ion battery. Although paper batteries are emerging as a thinner version candidate, [9] they are still based on conventional metallic materials, which are neither stretchable nor compressive, unable to conformally be attached onto human skin. Typical smart soft electronics including wearable glucose sensors, pressure sensors, and surface electromyography (sEMG) only require a voltage of <100 mV and a power consumption of <20 µW, which could be supplied by different types of energy devices. [10] In this context, a variety of soft energy devices based on nanomaterials including batteries, [11] supercapacitors, [12,13] solar cells, [14] triboelectric nanogenerators, [15] and fuel cells [16-18] have attracted tremendous attention as the potential replacement of the lithium-ion battery to power skin-like electronics. Each type of those energy devices has their own intrinsic pros and cons. Wearable supercapacitors cannot provide continuous long-term energy supplies; [12,13] the performance of wearable photovoltaic devices is highly dependent on the external light source; [14] and the wearable nanogenerators based on piezoelectric and triboelectric devices can only provide intermittent energy and must be integrated with energy storage devices for continuous long-term monitoring. [15] Stretchable enzymatic biofuel cell that uses glucose or lactic acid in the body fluid to generate energy has been considered as an environmentally friendly power source for the next-generation skin-like energy devices. However, its performance is largely dependent on the stability of the enzyme, which may be easily affected by body temperature, pH, and fuel concentrations. [19,20] In contrast, fuel cells that use ethanol or methanol as a model system could offer a much higher power density and stability as they are not influenced by the biological environments. [21] A number of materials including silver nanowires, [22] carbon fibers, [23] graphene paper, [24] nickel foam, [25] vertically aligned gold nanowires (V-AuNWs) [26] have been demonstrated to fabricate flexible or even stretchable fuel cells. Nevertheless, high power output, skin-like device thickness, Skin-like energy devices can be conformally attached to the human body, which are highly desirable to power soft wearable electronics in the future. Here, a skin-like stretchable fuel cell based on ultrathin gold nanowires (AuNWs) and polymerized high internal phase emulsions (polyHIPEs) scaffolds is demonstrated. The polyHIPEs can offer a high porosity of 80% yet with an overall thickness comparable to human skin. Upon impregnation with electronic inks containing ultrathin (2 nm in diameter) and ultrahigh aspect-ratio (>10 000) gold nanowires, skin-like strain-insensitive stretchable electrodes are successfully fabricated. With such designed ...

“…Fossil fuel exhaustion and environmental pollution have caused serious global concerns. Therefore, it is imperative to develop novel renewable sustainable and clean energy sources [1][2][3][4] such as solar cells, photovoltaic devices, hydrogen fuel cells, and bioenergy devices [5][6][7][8] . Owing to their solar independence and high unit capacity, hydrogen fuel cells are considered to be the most efficient renewable energy sources [ 9 , 10 ].…”
