A fuel cell device, comprising: a housing including a housing body that defines an inner space, two air guide tubes communicating with said inner space and suitable for respectively introducing hydrogen and oxygen into said inner space, and a drain pipe communicating with said inner space and suitable for draining water in said inner space; a runner plate disposed in said inner space and including a plurality of straight sections arranged in two rows which are spaced apart in a first direction, said straight sections of each row extending in a second direction transverse to the first direction and being spaced apart from each other in a third direction transverse to the first direction and the second direction, each two adjacent ones of said straight sections of each row defining an opening therebetween, said openings in said two rows of said straight sections being staggered with respect to each other, each of said straight sections having a width extending in the third direction greater than a width of each of said openings extending in the third direction, and having a plurality of penetrating holes spaced apart from each other along a length of a corresponding one of said straight sections, and a plurality of connecting sections each of which is connected between one end of one of said straight sections of one of said two rows and one end of a corresponding one of said straight sections of the other one of said two rows, each two adjacent ones of said connecting sections being connected to and cooperating with a common said straight section to define a drain channel extending in the second direction and communicating with said opening that aligns with said common straight section; two spaced-apart electrode plates disposed in said inner space such that said runner plate is stacked on and in contact with one of said electrode plates; and a proton exchange membrane clamped between said electrode plates. a housing including a housing body that defines an inner space, two air guide tubes communicating with said inner space and suitable for respectively introducing hydrogen and oxygen into said inner space, and a drain pipe communicating with said inner space and suitable for draining water in said inner space;
