A fuel cell uses the chemical energy of hydrogen or another fuel to cleanly and efficiently produce electricity. If hydrogen is the fuel, electricity, water, and heat are the only products.

The cost of materials is one of the biggest barriers for wastewater driven microbial fuel cells MFCs. Many studies use expensive materials with idealistic wastes. Realistically the choice of an ion selective membrane or nonspecific separators must be made in the context of the cost and performance of materials available. Fourteen membranes and separators were characterized for durability, oxygen diffusion and ionic resistance to enable informed membrane selection for reactor tests. Subsequently MFCs were operated in a cost efficient reactor design using Nafion, ethylene tetrafluoroethylene ETFE or polyvinylidene fluoride PVDF membranes, a nonspecific separator Rhinohide , and a no-membrane design with a carbon-paper internal gas diffusion cathode.

Cathodic oxygen reduction catalyzed by bacteria in microbial fuel cells

The fuel cell is an electrochemical device that can directly convert the chemical energy of fuels into electrical energy through a chemical reaction at the interface of the electrode and the electrolyte, without going through the heat engine process, and is not limited by the Carnot cycle, so the energy conversion efficiency is high without noise and pollution. Among them, the proton exchange membrane fuel cell PEMFC is a promising power source for electric vehicles and stationary residential applications. However, current PEMFCs have several problems that need to be solved, including high cost, insufficient power density, and limited performance durability. Therefore, to achieve large-scale application of PEMFCs, the development of advanced Pt-based catalysts is very important to solve these problems.

A microbial fuel cell MFC is a device to use for bio electrochemical energy production. Electrophilic bacteria produce electrons in their metabolic pathway and the electrons can be extracted and concentrated on electrode by the electric potential difference i. Galvanic cell. For the MFC technology to be adopted by industry requires a strategy for scaling up, which, in turn, requires a better understanding of the entire fuel cell system and the potential bottlenecks in the generation of electricity.

The oxygen reduction reaction ORR is one of the major factors that is limiting the overall performance output of microbial fuel cells MFC. Their performances were also compared to activated carbon AC based cathode under similar conditions. Microbial fuel cells MFCs are bio-electrochemical systems that can treat wastewater while simultaneously generating electricity. This co-generative configuration can theoretically replace the existing energy-intensive treatments plants [1] , [2]. Unfortunately, the performances of MFCs are limited by serveral factors that hinder its large-scale application [3] , [4] , [5]. It has been established that one of the main factors limiting the power output of MFCs is the reduction reaction in the cathode [6]. The most used oxidant at the cathode is oxygen, and this is due to the fact that oxygen has a high reduction potential, and is naturally abundant in the atmosphere.

Хейл остановился: - Диагностика? - В голосе его слышалось недоверие.  - Ты тратишь на это субботу, вместо того чтобы развлекаться с профессором. - Его зовут Дэвид. - Какая разница?. - Тебе больше нечем заняться? - Сьюзан метнула на него недовольный взгляд. - Хочешь от меня избавиться? - надулся Хейл.

Халохот продолжал двигаться. Расстояние между ним и Беккером быстро сокращалось. Он нащупал в кармане пиджака пистолет. До сих пор Дэвиду Беккеру необыкновенно везло, и не следует и дальше искушать судьбу. Пиджак защитного цвета от него отделяли теперь уже только десять человек.

Пальцы совсем онемели. Беккер посмотрел вниз, на свои ноги. До апельсиновых деревьев не меньше ста метров.

ТРАНСТЕКСТ все равно справился. - Время. - Три часа. Стратмор поднял брови.

Коммандер. Нет. Сьюзан словно окаменела, ничего не понимая. Эхо выстрела слилось с царившим вокруг хаосом.

 Но сейчас только без четверти. Двухцветный посмотрел на часы Беккера. Его лицо казалось растерянным.

 Как мило, - вздохнула. - Итак, твой диагноз? - потребовал. Сьюзан на минуту задумалась.

 - Ну прямо цирк.  - Он провел рукой по подбородку, на котором темнела полуторасуточная щетина.  - А что Следопыт.

 Сядь.  - На этот раз это прозвучало как приказ. Сьюзан осталась стоять. - Коммандер, если вы все еще горите желанием узнать алгоритм Танкадо, то можете заняться этим без. Я хочу уйти.

Она достаточно хорошо знала Танкадо и знала, что он боготворил простоту.
