New Zealand's (NZ) thirst for hydrocarbon-based fuels for transportation is rising exponentially, resulting in two severe consequences: first, severe emissions of greenhouse gases and a range of pollutants, and second, the dependence on foreign petroleum imports to provide those fuels. Thus there is a stimulus to develop, and to utilise, energy systems that are reliable and sustainable. The implementation of the hydrogen-based fuel cell (FC) system for electric vehicles (EVs) appears to be a promising solution because the FC is now established as a reliable, non-polluting energy source, having a high power density that competes favourably with the conventional internal combustion (IC) engine and the battery vehicle. This study provides a comprehensive review of the proton exchange membrane (PEM)-based FC, and assesses its potential in FC vehicles as an alternative to internal-combustion-based vehicles for NZ cities. The study indicates a need for FCs to penetrate the automotive market, plus key government and business strategies for the introduction of PEM EVs.

Mathematical modelling was developed for direct ethanol fuel cell (DEFC) by considering electrochemical reactions and mass transport. The model was validated against experimental data from previous research and showed good agreement with the data. The developed mathematical modelling for this research was based on the Butler-Volmer equation, Tafel equation and Fick’s law. The model was used to investigate parameters such as ethanol concentration and cell operating temperature. The developed mathematical model simulated the data from previous research. Ethanol concentration played a vital role to achieve high-performance DEFC. The higher the ethanol concentration, the higher current could be generated in DEFC. Nonetheless, the higher the usage of the ethanol concentration, the higher the ethanol crossover might occur. The highest current density produced from the fuel cell was at 21.48 mA cm-2, for 2M of ethanol concentration. Operating temperature also affected cell performance. The higher the operating temperature, the higher power density could be generated—the peak power density of 5.7 mWcm-2 at 75 oC with 2M of ethanol. As for ethanol crossover, the highest ethanol crossover was at 12.4 mol m-3 for 3M concentration of ethanol. It proved that higher ethanol concentration led to higher ethanol crossover.

“…In addition to the fact that the clinoptilolite-type zeolite catalyst used is efficient and allows obtaining electrical energy through the cell without using platinum-based catalysts which are expensive and quickly deactivate. The activity of the catalyst for the production of electrical energy through the micro-cell, using bioethanol as fuel, is attributed to the diversity of ions present in the zeolite such as: Ca, Mg, Al, Si, K, Fe; which some of them acting as co-supports and others as an active phase, allowing the oxidation of bioethanol in the anode and the reduction of oxygen in the cathode, according to the reactions proposed by Pethaiah et al (2016):…”

Currently, technological alternatives are being sought for the substitution of fossil fuels for different reasons.One of the most relevant is the protection of the environment, to have an improvement in this aspect, the generation of energy through clean sources is sought. The PEMFC (Proton Exchange Membrane Fuel Cell) type fuel cells are an excellent alternative for the generation of clean energy because the residues of the fuel cell are mainly water and heat. In the present work, clinoptilolite zeolite was used to produce clean energy by a fuel cell using bioethanol as fuel. Zeolite showed promising results when used in combination with carbon and hydrogel as a solid electrolyte. The material was characterized by scanning electron microscopy and x-ray electron microscopy. The result showed a maximum power of 0.00589241 mW in a surface of 900 mm2 , which is considered a positive result. The catalyst is functional to produce energy by an electrooxidation reaction using bioethanol in a fuel cell at a low cost compared to traditionally platinum-based catalysts.
