Abstract
An oxidizer catalyst assembly for use in a fuel cell system for oxidizing anode exhaust gas and in which a first catalyst member is situated along a gas flow path and a second catalyst member is situated along the gas flow path following the first catalyst member. Each of the catalyst members includes a plurality of channels for passing the gas therethrough and an oxidizing catalyst deposited in the channels. The channel density of the channels of the second catalyst member is greater than the channel density of the channels of the first catalyst member and the channel width of the channels of the second catalyst member is less than the channel width of the channels of the first catalyst member.
Claims9
A fuel cell system including an oxidizer catalyst assembly for oxidizing an anode exhaust output from an anode of a fuel cell of the fuel cell system, said oxidizer catalyst assembly comprising:
- a first catalyst member arranged along a gas flow path;
- a second catalyst member arranged along said gas flow path following said first catalyst member;
- each of said first and second catalyst members including a plurality of through channels for passing gas therethrough and an oxidizing catalyst in each of said through channels;
- and said channels of said second catalyst member having a channel density which is greater than the channel density of said channels of said first catalyst member and a channel width which is less than the channel width of said channels of said first catalyst member.
