Abstract
In an air cell a current collector is so disposed between a cathode and an anode that it is in contact with the cathode. The air cell can thus be compact and lightweight and yet is capable of generating a high power output under low internal resistance. Furthermore, the cathode has a plurality of spaced-apart sections or at least one through-hole to facilitate the release of hydrogen.
Claims5
An air cell comprising a cathode;
- an anode having a comb-like shape so that a plurality of openings are defined therethrough;
- and means for collecting electrons generated at said anode, said means comprising a current collector and contacting said cathode at a surface thereof facing toward said anode.
An air cell comprising an anode;
- a cathode having a plurality of spaced-apart sections or at least one through-hole extending therethrough;
- and a porous water-repellent body to which said cathode is mounted.
