Liquid fuel cell

DETAILED DESCRIPTION We claim: 1.
A liquid fuel cell comprising: an anode made of carbon powders carrying an electrode catalyzer, said anode being adapted to be supplied with a liquid fuel and having as a whole a homogeneous and porous structure which has a porosity of 65-85% and in which pores of 20-100 .
mu.
m occupy at least thirty percent of the total pore volume of said homogeneous and porous structure; a gas-permeable cathode supplied with an oxidizer; a separator interposed between said anode and said cathode; and a casing for accommodating therein said anode, said cathode, said separator and an electrolyte, said electrolyte existing at least in said separator.
2.
A liquid fuel cell according to claim 1, wherein said carbon powders forming said anode have their particle diameters not larger than 297 .
mu.
m which pass through a 50 Tyler mesh but at least thirty percent by volume of said carbon powders have their particle diameters larger than 149 .
mu.
m which are unable to pass through a 100 Tyler mesh, and said carbon powders are bonded with a binder.
3.
A liquid fuel cell according to claim 2, wherein said carbon powders contain one volume of carbon powders larger than 149 .
mu.
m and not larger than 297 .
mu.
m which pass through a 50 Tyler mesh but are unable to pass through a 100 Tyler mesh, and 0.
5 to 1.
5 volumes of carbon powders larger than 44 .
mu.
m and not larger than 74 .
mu.
m which pass through a 200 Tyler mesh screen but are unable to pass through a 325 Tyler mesh.
4.
A liquid fuel cell according to claim 3, wherein said anode contains 100 parts of said carbon powders and 10 to 35 parts of said binder by weight.
5.
A liquid fuel cell according to claim 4, wherein said binder is selected from the group consisting of polytetrafluoroethylene, polyethylene, polystyrene, polyvinyl chloride and polyvinylidene chloride.
6.
A liquid fuel cell according to claim 1, further comprising means for feeding a liquid fuel to the anode.
7.
A liquid fuel cell according to claim 6, wherein said means for feeding a liquid fuel to the anode feeds the liquid fuel to the surface of the anode opposite the surface adjacent the separator
