Highlights• Self-produced H2 from electrodialytic treatment of environmental matrices collected • Collected H2 average purity (% mol/mol) of ≈ 98%• A fuel cell used to produce electricity from the self-produced H2 (~1 V)• Experimental self-generated energy promotes savings on electroremediation (≈ 7%) AbstractElectrodialytic technologies are clean-up processes based on the application of a low-level electrical current to produce electrolysis reactions and the consequent electrochemically-induced transport of contaminants. These treatments inherently produce electrolytic hydrogen, an energy carrier, at the cathode compartment, in addition to other cathode reactions. However, exploring this by-product for self-energy generation in electroremediation has never been researched. In this work we present the study of hydrogen production during the electrodialytic treatment of three different environmental matrices (briny water, effluent and mine tailings), at two current intensities (50 and 100 mA). In all cases, hydrogen gas was produced with purities between 73% to 98%, decreasing the electrical costs of the electrodialytic treatment up to ≈ 7%. A protonexchange membrane fuel cell was used to evaluate the possibility to generate electrical energy from the hydrogen production at the cathode, showing a stable output (~1 V) and demonstrating the proof of concept of the process.

“…The water flux in the membrane occurs through three main mechanisms, namely the electro-osmotic drag effect (EOD) of dissolved water accompanied by protons moved in the membrane, 35,36 water dispersion driven by water concentration gradients, 37 included transfer convective due to the pressure gradient between the anode and cathode 38 called hydraulic permeation. 39,40 Several studies of Huang et al 41 showed that when anode gas reactant is moistened, the EOD result will influence the water delivery operation. On the other hand, if cathode reactor gas is dampened, back diffusion will have an important role.…”

A review of alternative polymer electrolyte membrane for fuel cell application based on sulfonated poly(ether ether ketone)

A proton exchange membrane (PEM) is a crucial component in a fuel cell application as a proton carrier and separator for the anode and cathode. Sulfonated poly(ether ketone ether) (SPEEK) has been recognized as one of the promising alternatives PEM in fuel cell application due to the advantagious properties of SPEEK, including the high thermal stability, proton conductivity, mechanical strength, low fuel crossover, and easy to operate. The proton conductivity properties of SPEEK are influenced by the degree of sulfonation (DS). In practical, high DS of SPEEK-based membrane will produce high proton conductivity and a high density of sulfonic acid functional groups grafted into the polymer backbone. However, the excessive production of DS will have side effects on the stability of membrane dimensional and chemical properties.Meanwhile, the low DS of SPEEK has reduced the ability to diffuse the proton within the polymeric matrix. Therefore, getting the optimal DS SPEEK is very important to fabricate the alternative of PEM. But this process is hard. Thus, the researchers have modified the SPEEK membrane with various types of nanoparticles as a filler. This is one of the promising efforts to improve the SPEEK membrane properties and fuel cell application performance. This review aimed to discuss eight conductive materials such as silica, clay, metal oxide, heteropolyacids, carbon, graphene, metal organic framework, and zeolite used as fillers to develop the PEM component based on SPEEK for fuel cell applications. This review also comprehensively discusses the characterization of SPEEK-based membrane modification, including mechanical properties, water intake, proton conductivity, thermal properties, fuel permeability, crystal and structural analysis, chemical oxidation stability, and single-cell performance. Thus, this article can serve as a reference for researchers to planning the best strategies to optimize the properties and performance of the SPEEKbased membrane for fuel cell application.

“…FCs can be categorized into various types depending on the type of fuel used, operating temperature range and nature of chemicals used as an electrolyte. 37,38 Basing on the above factors FCs are classified into six types for utilization in energy generation [39][40][41] such as: (a) proton exchange membrane FC (PEMFC); (b) solid-oxide FC (SOFC); (c) direct methanol FC; (d) phosphoric acid FC; (e) alkaline FC and (f) molten carbonate FC. Figure 3 describes the application of various FCs for grid operation basing upon the rating of power generation capability and advantages.…”
