Abstract
A fuel cell stack and a fuel cell system using the same are disclosed. The fuel cell stack may include an electricity generation unit generating electrical energy by an electrochemical reaction of fuel and oxidizer. The fuel cell stack may include a regulation member made of porous materials to disperse coolant flowed in through a cooling channel formed in the fuel cell stack.
Claims17
A fuel cell stack, comprising:
- a plurality of electricity generation units, wherein each electricity generation unit comprising a membrane electrode assembly disposed between two separator layers, and wherein each electricity generation unit is configured to induce an oxidation-reduction reaction of the fuel and oxidizer;
- and
- a regulation member disposed over at least part of the plurality of electricity generation units, wherein the regulation member is formed of a porous material in a plate shape and wherein the regulation member is disposed adjacent to a cooling channel and is in fluid communication with an inlet end of the cooling channel.
A fuel cell system, comprising:
- a fuel cell stack;
- a fuel supplier connected to the fuel cell stack;
- an oxidizer connected to the fuel cell stack;
- a regulation member disposed over at least part of the fuel cell stack, the regulation member formed of a porous material in a plate shape;
- and
- an electricity generation unit portion of the fuel cell stack, wherein the electricity generation unit comprises a plurality of membrane electrode assemblies, each membrane electrode assembly disposed between at least two separator layers, wherein the regulation member is disposed over the plurality of membrane electrode assemblies and wherein the regulation member is in fluid communication with and configured to disperse coolant flowed through a cooling channel formed in the fuel cell stack.
