Finally, an example application of the evolution of grain boundary porosity in nuclear fuel is shown in the "Example application to grain boundary porosity in nuclear fuel" section.
A model of a system including a proton exchange membrane (PEM) fuel cell and its fuel processing section has been developed.
The proposed system, operated on natural gas, consists of a planar anode supported fuel cell section and a balance of plant (BoP) which includes gases supply, a fuel processor, a heat management system, an after-burner and a power conditioning system.
"It was all meant for an interim solution," said John Monninger, chief of the commission's spent fuel licensing section.
Then came palm oil; in an effort to reduce reliance on fossil fuels, extensive sections of coastal areas were converted into palm oil plantations to produce biofuel.

The 'Microbial fuel cells' section explains the construction, operation and classification of current MFC designs, and the 'Current directions of MFC research' section reviews the issues being addressed in current MFC research.
As mentioned before in the 'Microbial fuel cells' section, they are both capable of being used for DET mode in MFCs, because both Shewanella sp. and Geobacter sp. possess nanowires, electrically conductive bacterial appendages, to transport electrons from cells to solid electron acceptors such as graphite anodes in MFCs [34, 35, 162].
This Geobacter species can produce large amounts of electrical energy since it possesses multiple mechanisms that involve either pili or c-type cytochromes to facilitate the electron transfer to electrode in MFCs (discussed before in the 'Microbial fuel cells' section) [149].
Also there is a growing culture of suing doctors because of malpractice claims, and this may fuel cesarean section rates as a form of 'defensive' medical practice.
