	Toshiba's methanol fuel cell: Digital Photography Review
		At a compact 22 x 56 x 4.5mm (maximum of 9.1mm, for the fuel tank), the slim prototype DMFC is as long and wide as a woman's thumb, a size advantage that will give greater design freedom for developers of handheld electronic devices.
		However, passive DMFC have a simpler structure that requires no pump or fan, and use the concentration gradient to deliver and circulate methanol and oxygen in the cell stack.
		As the result, Toshiba's new DMFC realizes a fuel tank less than 1/10 the size of that required for storing the same volume of methanol in a concentration of less than 10%.

	Types - Direct Methanol Fuel Cells (Site not responding. Last check: 2007-10-13)
		DMFC is similar to the PEMFC in that the electrolyte is a polymer and the charge carrier is the hydrogen ion (proton).
		However, the liquid methanol (CH OH) is oxidized in the presence of water at the anode generating CO, hydrogen ions and the electrons that travel through the external circuit as the electric output of the fuel cell.
		One of the drawbacks of the DMFC is that the low-temperature oxidation of methanol to hydrogen ions and carbon dioxide requires a more active catalyst, which typically means a larger quantity of expensive platinum catalyst is required than in conventional PEMFCs.

		For all its promise, DMFCs are yet to appear on the market although NEC has said it expects to commercialize a product for notebook computers sometime in 2004.
		DMFCs for smaller devices like mobile telephones or PDAs are being developed now and are expected sometime within the next one to three years, according to estimates from companies developing the technology.
		Miniaturizing the DMFC and extending its life means using a higher concentration of methanol, although that has caused problems with the membrane and some wastage of methanol.

	Techworld.com - Why are fuel cells better than batteries?
		Traditional DMFC systems, also known as active systems, include a condenser, fans, pumps and fluid-mixing circuits to dilute the methanol as it is fed to the anode side of the fuel cell.
		The fuel cell is akin to a chemical sandwich with layers of catalysts and membranes between an anode and a cathode layer.
		A passive design requires the DMFC platform to manage water in a way that obviates the need for condensing the vapor from the cathode exhaust, then storing and mixing it with methanol to maintain an accurate concentration of methanol and water at the anode.

		Furthermore, byproducts of DMFC are ecologically harmless CO and water.
		These are the reasons why the DMFC system has been considered as a potential substitution to traditional batteries for powering various micro-systems or portable devices.
		During the operation of the DMFC system, the methanol concentration is monitored using a methanol concentration sensor and the feedback is provided to the control valve of the methanol reservoir.
