Possibility of Wastewater Treatment Using MFC with Ni-Co Catalyst of Fuel Electrode

2016

Abstract One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for fuel electrode (anode) - as long as a low cost catalyst can be found. The possibility of wastewater treatment using the Ni-Co alloy as catalyst for MFC’s is presented in this paper. The alloys were obtained with different concentrations of Co (15 and 50% of Co). The increase of current density with Ni-Co catalyst is approximately 0,1 mA/cm2. So, a fundamental possibility wastewater treatment using the Ni-Co alloy as catalyst for microbial fuel cells was presented.

Nanostructured Ni-Co Alloy Electrodes Fabrication and Characterization for both Hydrogen and Oxygen Evolution Reaction in Alkaline Electrolyzer

2019

Sun and wind as power sources are becoming more and more relevant owing to the progressive abandoning of the fossil fuels [1,2]. Additionally, worldwide public authorities are encouraging the use of renewable energies by promoting laws and guidelines [3,4]. In this scenario, a fundamental role can play hydrogen that besides being a valuable energy carrier, it can also act as a storage medium to balance the discontinuity affecting the renewable energy sources production [5]. As a consequence, cheap and abundant availability of hydrogen is crucial. Electrochemical water splitting is likely one of the most valuable technique to produce hydrogen because the process is environmentally friendly b…

Microbial fuel cell with Ni-Co cathode

2017

Wraz ze wzrostem poziomu życia wzrasta zarówno zużycie energii, jak i ilość ścieków. Istnieje jednak możliwość produkcji energii z jednoczesnym oczyszczaniem ścieków. Urządzeniem, które może zrealizować to zadanie jest mikrobiologiczne ogniwo paliwowe. W ogniwach tego typu bakterie osadu czynnego wykorzystane są do produkcji energii podczas oczyszczania ścieków. Jednym z ograniczeń tego rozwiązania jest niska gęstość uzyskiwanego prądu. Możliwe jest jednak podwyższenie tego parametru przy wykorzystaniu odpowiedniego katalizatora elektrod. W artykule przedstawiono możliwość wykorzystania stopu Ni-Co jako katalizatora katody. Badania obejmowały przygotowanie elektrody oraz porównanie zmian st…

USE OF Ni-Co ALLOY AS CATHODE CATALYST IN SINGLE CHAMBER MICROBIAL FUEL CELL

2017

Technology of microbial fuel cells allowing for the direct production of electricity from biodegradable materials can provide only energy production, but also wastewater treatment. This technology is seen as supporting of the traditional wastewater treatment. One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for electrodes (anode and cathode). The possibility of wastewater treatment using the Ni-Co alloy as catalyst for single chamber microbial fuel cells is presented in this paper. The studies have included measurements of H2O2 reduction on Ni-Co catalyst, power o…

Microbial fuel cell with Cu-B cathode and KMnO4 catholyte

2017

The increasing of standard living causes the increases energy consumption and waste or wastewater production. The possibility to combine wastewater treatment and electricity production can accomplish a microbial fuel cell. The possibility of wastewater treatment using the Cu-B catalyst with KMnO4 catholyte for microbial fuel cells is presented in this paper. The measurements covered comparison of changes in the concentration of COD, NH4+ and NO3- in the reactor without aeration, with aeration and with using a microbial fuel cell (with Cu-B cathode and KMnO4 catholyte). The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (and KMnO4 catholyte) is similar to t…

Wykorzystanie stopu Ni-Co jako katalizatora katody w jednokomorowym mikrobiologicznym ogniwie paliwowym

2017

Technologią, która wykorzystuje ścieki jako surowiec, zapewniając jednocześnie ich oczyszczanie oraz produkcję prądu, jest technologia mikrobiologicznych ogniw paliwowych. Technologia ta postrzegana jest jako wspomaganie tradycyjnego oczyszczania ścieków. Jednym z podstawowych problemów związanych z mikrobiologicznymi ogniwami paliwowymi jest niewielka ilość produkowanej energii elektrycznej. Gęstość prądu zależy od szybkości zarówno reakcji anodowych, jak i katodowych. Celem pracy było wykazanie możliwości wykorzystania stopu Ni-Co jako katalizatora elektrody tlenowej w jednokomorowym mikrobiologicznym ogniwie paliwowym. Badania objęły pomiary szybkości rozkładu H2O2 na analizowanym katali…
