Hitachi Maxell invents electrode catalyst using cheaper material

Publication Date: 20-July-04
Source: Asia Pulse

HITACHI MAXELL LTD. (TSE:6810) has developed a new type of electrode catalyst that promises to lower the overall cost of tiny fuel cells for portable information devices by around 10 per cent. Fuel cells use a catalyst to promote the reactions at the electrodes, which extract hydrogen ions from methanol and oxygen ions from air.

* For efficiency and long service life, platinum is the catalyst of choice, however, it is rare and expensive.

* The new catalyst is made from molybdenum oxide, which can be purchased for as little as 1/100 the cost of platinum.
