Polarization curve using LSV PDF Print E-mail
Monday, 04 February 2013


I am a student doing research on MFC. I am plotting the polarization curve using linear sweep voltammetry. I connected the working electrode to the cathode and the reference and counter to the anode. Is it correct? I use a scan rate of 1mV/s. Is the scan rate important? The problem is my result is getting negative current but my potential is positive. Is this possible? Can someone tell me the problem?

Thank you for your help.

Hello I am building a mediator-less PEM microbial fuel cell for a science project. All of the publications and other experiments I have seen measures the output in W/m^2. How is this number achieved? Can I divide the watts by the surface area of my anode electrode? Or is this not the correct unit to be using? Thanks!

pH related questions PDF Print E-mail
Saturday, 17 November 2012

Dear sir,

i am working in MFC with distillery effluent as substrate and K3FeCN6 as cathode. after 5th day of my experiment,anode pH is increased.i would like to know why it is increased? most of the papers reported that, pH will decrease after few days of operation.please answer the above questions.

Can we use basillus type of bacteria used as biocathode in the cathode compartment? 

Cathode catalyst layer PDF Print E-mail
Tuesday, 30 October 2012

Dear all,

Currently I'm focusing on cathode catalyst in single chamber fuel cell.

If I make large pices cathode with the proper catalyst (CoTMPPor FePC) layer, is there any way to preserve it with no chance of damage??and how to preserve with care??What kind of chemical do I need to use. Full procedure will be better.

Thank you. 

Low current PDF Print E-mail

I have build a MFC , i am using the pencil lead as the cathode and anode. the Voltage(potential difference) is about 0.1-0.2 volts, i m not using the air pump for the cathode. Base on the ohms Law V=I/R.. the current that i obtain sholud be 10mA or 0.01 A if 10ohms resistor is connect to the MFC...but what i get is just 0.00001A or 0.01mA......

Anode and Cathode material properties PDF Print E-mail
Friday, 24 August 2012

I have a relatively easy question and I hope someone can answer. Does the Cathode have to be more electropositive than the Anode? Is it OK to use the same materials for the Anode and Cathode?


Methane production using microbial electrolysis cells PDF Print E-mail
Thursday, 15 March 2012


I'm working with my daughter on her science fair project and she is hoping to try and show how it is possible to produce methane using wastewater, microbes, and electricity generated from a solar panel.

We got the idea from an article we found online:


Can you give us any advice on how to proceed?  So far I haven't been able to find any follow up information on the research discussed in the article.  One of the primary concerns we have is to identify the major obstacles hindering the commercial adoption of this technology.


Any help you can give is greatly appreciated!



Electrochemistry question PDF Print E-mail
Monday, 27 February 2012
 I got a relatively simple question. In order to calculate E(anode) one needs standard electrode potential for butyrate and put it into Nernst equation. Firstly a) I can not find  standard electrode potential anywhere. I would appreciate if someone cold provide me with the value and b)  do you agree with what’s written in the equation?

Si usted es un principiante en este tipo de tema, entonces esto va a ser una gran gu¨ªa para usted. El mejor m¨¦todo de disuasi¨®n de ganso es la que el se adapte a su situaci¨®n. En otras palabras, algunos m¨¦todos funcionan mejor para algunas personas y algunos funcionan mejor para los dem¨¢s. Sin embargo, siempre me gusta empezar desde lo m¨¢s b¨¢sico de t¨¢cticas para los m¨¢s canada goose outlet avanzados. Realmente no me gusta escribir art¨ªculos de pelusa, as¨ª que vamos a ir al grano de acuerdo? En primer lugar, no alimentar a los gansos. Esto hace que sea m¨¢s f¨¢cil para deshacerse de ellos si no tienen una raz¨®n para seguir volviendo a su propiedad para la comida. Otra gran repelente de ganso es un se?uelo coyote. El coyote se ha sabido para matar a un mont¨®n canada goose outlet coats de gansos y por lo tanto es natural que temer este depredador. Si se implementa el uso de estos se?uelos, entonces aseg¨²rese de moverlos cada cierto tiempo para que los p¨¢jaros no se acostumbren a ellos. Se?uelos de cabeza de cocodrilo tambi¨¦n funcionan muy bien en los estanques y lagos.

Otro gran m¨¦todo para mantenerlos fuera de un c¨¦sped es el movimiento activado canada goose por aspersi¨®n. Estos son realmente eficaces en el mantenimiento de estos p¨¢jaros molestos se implante sus heces por todo el lugar. Si se ponen dentro de la gama de estos dispositivos, entonces van a quedar rociado con chorros de alta presi¨®n de agua y sale volando. Otro gran m¨¦todo es los productos qu¨ªmicos. Me gustan los que son seguros para el medio ambiente. Estas canada goose outlet online cosas hacen una de dos cosas. Algunos de ellos causan los gansos para obtener indigesti¨®n; los otros simplemente tienen mal sabor a ellos. Tenga en cuenta, que la mayor¨ªa de estos elementos disuasorios l¨ªquidos no da?an a los gansos. De hecho, no he o¨ªdo hablar de ninguna de ellas dificultando a los p¨¢jaros. De todas formas, el m¨¦todo repelente ¨²ltima gallina que me canada goose sale gustar¨ªa hablar es de la unidad de agua. Es ampliamente conocido que estas aves suelen dormir en estanques y lagos. Los que tienen este problema en particular podr¨ªa utilizar una unidad de agua que tiene una luz muy parecida a la de la parte superior de un coche de polic¨ªa o una casa de la luz. Se da vuelta y hace tan inc¨®moda que no pueden dormir y terminan dejando.
