Abstract: The present invention relates to a method for preparing a heteropolyacid catalyst and method for preparing methacrylic acid using thereof. More particularly, the present invention relates to a method for preparing heteropolyacid catalyst, which is produced by the recrystallization of a heteropolyacid and/or its salt dissolved in a basic organic solvent and heat-treatment, and further to a method for preparing metachrylic acid using thereof, wherein the use of the heteropolyacid catalyst increases the activity of oxidation reaction induced by the modified electronic properties of heteropolyanions and provides high efficiency production of methacrylic acid from methacrolein, since the basic property of solvent inhibits peculiar acidic property of heteropolyacid.

Abstract: An internal reforming molten carbonate fuel cell having a membrane for intercepting carbonate vapor and hydrated vapor is disclosed. The intercepting membrane is made from nickel or nickel alloy which has a high electrical conductivity, corrosion resistant property in an anode environment, and a low affinity for the carbonate vapor. Due to the presence of the intercepting membrane, the transfer of the carbonate vapors and hydrated vapors to the internal reforming catalyst is markedly retarded to prolong the catalytic activity. As a result, a longer operating molten carbonate fuel cell can be obtained.

Abstract: A perforated gas-distributing plate for compact fuel cells made of a metal material such as stainless steel on which gas flow paths are formed by an etching process, and a separator plate manufactured using the gas-distributing plate are disclosed. The separator plate manufactured using the gas-distributing plate may possibly be thinner and no more susceptible to breakage by an externally applied force due to its higher physical strength, compared to conventional graphite separator plates. In addition, since the gas channels formed on the gas-distributing plate have the same dimension, contact resistance decreases and thus the performance of fuel cell increases. Furthermore, since the separator plate is made of a metal material such as stainless steel, cost and manpower are reduced when etching the separator plate, and thus mass production of the separator plate is possible. Therefore, compact fuel cells comprising the separator plate are advantageous in terms of power density, reliability and economic efficiency.
