Talk:Molten carbonate fuel cell

Untitled
The current wording in this article suggests that this fuel cell can convert carbon into hydrogen. This is, of course, ridiculous as no chemical process can transmute one element into another.

Problem durability
MTU Friedrichshafen claims around 30.000 hours. That's more than 3 years. The degrading comes suddenly, so over all the time nearly constant efficieny. More would be nice, but I think 30.000 hours are not a big durability problem. --Pege.founder 19:02, 29 July 2006 (UTC)

Fuelcell Energy is now claiming their MCFC stack life is 5 yearsFuelcell Energy Service Agreement Brochure. I think MTU abandoned their MCFC development for a while several years ago after they were sold by DaimlerChrysler. This article should mention Fuelcell Energy somewhere as prominent in commercializing MCFCs. I am somewhat new to editing Wikipedia articles; Can someone guide me on including this info and what constitutes proper external references? Obviously, we don't want to rely on Fuelcell Energy's website. Dag in va (talk) 12:44, 8 April 2012 (UTC)

Get rid of corporate advertising
There apears to be corporate advertising filling the technology description section.

Broken Link
Link to the first reference seems to be broken - I can't access the linked article. Please check. --Monsieur.lefou (talk) 17:01, 6 December 2009 (UTC)

Possible copyvio?
Nearly all of the first section was copied verbatim from http://www1.eere.energy.gov/hydrogenandfuelcells/fuelcells/fc_types.html#molten

This is the edit:
 * https://secure.wikimedia.org/wikipedia/en/w/index.php?title=Molten_carbonate_fuel_cell&diff=26899527&oldid=26736915

Editor Tirronan notes that "understand I have to completely revise it.", however, that never happened:
 * https://secure.wikimedia.org/wikipedia/en/w/index.php?title=Molten_carbonate_fuel_cell&diff=458061739&oldid=26899527

Now this may not technically be a copyvio because it seems to be a US Government publication, and hence not subject to copyright. But still ... -- 203.20.101.203 (talk) 07:27, 7 December 2011 (UTC)


 * I am confused because the copyvio template is dated 2014 but the comment above dates from 2011. Anyway, I have checked the website in question and it does belong to the U.S. Department of Energy. In its web policies page it is stated that "Government information at DOE websites is in the public domain (...) but it is requested that in any subsequent use the Department of Energy be given appropriate acknowledgement." The latter does not seem compatible with the concept of public domain but it is not a problem for us, as the text should cite the DOE website as its source. So, I propose to remove the copyvio template and add the DOE website as reference for each of the four paragraphs of the introduction that have been copied from it. --Hispalois (talk) 13:50, 5 May 2017 (UTC)

Internal Reforming
I'd like to add the following to the paragraph that discusses internal reforming: The internal reforming process, being endothermic helps cool the fuel cell stack. National Fuel Cell Research Center It is capable of producing more hydrogen gas from the hydrocarbon fuel than the fuel cell consumes, utilizing the waste heat from the fuel cell to produce hydrogen as a byproduct, as is being demonstrated by Orange County, CA Sanitation Dept using Anaerobic digestion gas US DOE Report.

Carbon sequestration?
Can we add a paragraph about carbon capture? There are proposals SciVerse/SciTopics to use the cathode reaction of molten carbonate fuel cells to capture and concentrate CO2 from the flue gas of fossil fueled power plants. Dag in va (talk) 13:28, 8 April 2012 (UTC)

materials - anode
It says:

"The anode material typically consists of a porous (3-6 μm, 45-70% material porosity) Ni based alloy. Ni is alloyed with either Chromium or Aluminum in the 2-10% range. These alloying elements allow for formation of LiCrO2/LiAlO2 at the grain boundaries, which increases the materials' creep resistance and prevents sintering of the anode at the high operating temperatures of the fuel cell.[5]"

Should this really be "LiCrO2/LiAO2". Its not clear where the Li came from? Is it alloyed with the electrode or coming from a lithium carbonate electrolyte? — Preceding unsigned comment added by 192.55.54.41 (talk) 23:12, 11 January 2018 (UTC)

Mixed carbonate electrolyte. It's in the reference 128.84.183.251 (talk) 15:56, 1 May 2018 (UTC)

Efficiency
These statements appear conflicting: Darsie42 (talk) 14:39, 3 March 2019 (UTC)
 * Molten carbonate fuel cells can reach efficiencies approaching 60%.
 * Current MCFC efficiencies range from 60-70%.
 * Depending on feed gas type, the electric efficiency is between 12% and 19%.
