Abstract
A composition is provided that can be used, for example, in a fuel processor for a fuel cell system. The composition includes a first material such as a catalyst, and a second material such as a desiccant. The second material is capable of sorbing and desorbing a heat transfer material such as water, and is present in an amount sufficient to sorb an amount of the heat transfer material sufficient to remove a portion of the heat generated when the first material undergoes an exothermic reaction.
Claims45
A composition, comprising:
- (a) a first material;
- and
- (b) a second material capable of sorbing and desorbing a heat transfer material, the second material present in an amount sufficient to sorb an amount of the heat transfer material sufficient to remove a portion of the heat generated when the first material undergoes an exothermic reaction, wherein the first material and the second material comprise a mixture.
An article, comprising:
- a fuel processor for a fuel cell system;
- and
- a catalyst composite, the catalyst composite comprising a first material capable of undergoing an exothermic reaction and a second material capable of sorbing and desorbing water;
- and
- wherein the catalyst composite is disposed within an interior of the reformer.
A low temperature shift catalyst, comprising:
- a granule comprising a first amount of CuO, a second amount of ZnO, and a third amount of desiccant material, the third amount of desiccant material having a weight percent equal to or greater than a combined first and second amounts of CuO and ZnO.
A composition, comprising:
- (a) a first material;
- and
- (b) a second material capable of sorbing and desorbing a heat transfer material, the second material present in an amount sufficient to sorb an amount of the heat transfer material sufficient to remove a portion of the heat generated when the first material catalyzes an exothermic reaction, wherein the first material and the second material comprise a mixture.
A method of regulating temperature within an exothermic reaction, comprising:
- (a) providing a mixture of a first material capable of undergoing an exothermic reaction and a second material capable of sorbing and desorbing a heat transfer material;
- and
- (b) desorbing from the second material a portion of the heat transfer material sufficient to remove a portion of the heat generated when the catalyst material undergoes an exothermic reaction.
