“…Glycerol is a surplus byproduct of biodiesel production, which requires application in order to avoid inadequate disposal and to increase its market price . The presence of three hydrated carbons in its chain makes this alcohol a possible fuel for fuel cells and potential substrate for electrolysis . However, challenges must be surpassed to allow high energy production and/or selective electrolysis, indicating a need for new catalysts.…”

Here, we built Ru‐decorated Pt/C nanoparticles with different coverage degrees (θRu) by wall‐jet configuration for the first time, and we investigated their catalytic properties towards glycerol electrooxidation in acidic medium. Moreover, we used the most active catalysts as the anode in electrolysis to produce carbonyl compounds. The use of an electrochemical cell in wall‐jet configuration allows for the controlling of electrodeposition through easily handling parameters; namely, the θRu is controlled by changing the concentration of the metallic precursor, speed, and volume of injection onto a Pt/C‐modified glassy carbon electrode under applied potential. Excess of Ru on a Pt surface inhibits glycerol dissociative adsorption, which limits further electrooxidation; whereas low θRu do not provide surface oxygen species to the anodic reaction. Hence, intermediates θRu reveal active catalysts – namely, θRu=0.42 shifts the onset potential 170 mV towards lower values and increases 1.65‐fold the current density at 0.5 V. The stability of this catalyst is also enhanced by maintaining a more constant current density during successive potential cycles in the presence of glycerol and by avoiding Ru leaching from the surface. The electrolysis on Ru‐decorated Pt/C is shown to lead the reaction towards formic acid (‘high oxidation state’), decreasing the amounts of glyceradehyde, glycolic acid, and dihydroxyacetone, as a result of the improved catalytic properties.

“…The polarization curves showed (Figure ) that all systems exhibited an open‐circuit voltage (OCV) near to 0.6 V, as expected due to the similar glycerol oxidation peaks seen on the half‐cell voltammograms (Figure ). This OCV is lower, however, than those previously reported for a glycerol fuel cell , . This effect may be related to a low concentration of oxygen, as well as to the establishment of a mixed potential at the cathode in the type of passive micro fuel cell used .…”

This paper addresses energy generated in a passive anion‐exchange membrane micro fuel cell (PAEMμFC) using glycerol from several kinds of sources: high‐purity glycerol (HPG), saponification process‐derived glycerol (SPDG), crude glycerol from sunflower oil biodiesel (CGSOB) and crude glycerol from cooking oil biodiesel (CGCOB). Spectrophotometry, volumetric Karl Fischer, gas chromatography, calorimetry, Fourier transform infrared, and cyclic voltammetry were employed for the glycerol samples characterization. The PAEMμFC was tested using 0.1M glycerol of each type, achieving power densities of 1.008, 0.932, 0.871, and 0.865 mW cm−2 for HPG, SPDG, CGSOB and CGCOB, respectively. On the other hand, commercially available software from ANSYS, Inc. was used to determine the fuel velocity and pressure in the fuel reservoir and current collector as a complementary evaluation of the PAEMμFC. The results obtained for the prices of the energy of each glycerol sample were presented in order to demonstrate that the cost of energy generated through HPG is approximately 16.5 times the SPDG energy cost and 130 times the CGCOB energy cost.

“…LFµFCs operate by using an anode and a cathode, as it is for a conventional fuel cell; however, they dispense the use of an ionic permeable membrane. The performance of LFµFCs with glycerol as the fuel was evaluated and the results were promising [137][138][139][140]. Table 4.…”

The low price, highly active triol structure, high volumetric energy density, simple storage and environment-friendly properties make glycerol a promising fuel for an alkaline direct alcohol fuel cell (ADAFC). Unlike other ADAFCs, alkaline direct glycerol fuel cells (ADGFCs) can be used either to generate only energy (the common use of fuel cells) or to produce both energy and valuable chemicals. This work presents an overview of catalysts for glycerol oxidation in alkaline media, and their use in ADGFCs. A particular attention was paid to binary and ternary catalysts able both to increase the selectivity to valuable C3 glycerol oxidation products, reducing the C-C bond cleavage, and simultaneously to enhance glycerol conversion.
