Introduction Up to now PtRu alloys seem to be the favorite choice for the anode material in direct methanol fuel cells.[1-3] In spite of pure Pt is a higher electrocatalyst in all the metals, it must bears its disadvantages.

Introduction Intermetallic matrix composites (IMCs) can be considered to be one of the promising candidate materials for high temperature structural applications due to their high melting point, low density, good environmental stability and excellent oxidation resistance [1].
Ni3Si intermetahics have an excellent potential to become one of the most important high temperatures materials because of their low density, high melting temperature, good elevated temperature strength and modulus retention, and excellent creep properties.Although studies have been done to characterice in Ni3Si-base alloy ,there are limited oxidation data available for the alloy at elevated temperature [2-4].
