Abstract
A float type metal-air battery having an air chamber covered by an air pervious, water repellent membrane is provided with a protector lid to enclose the membrane. The lid includes at least one air intake opening. Shelter plates are interposed between the openings and the membrane to thereby prevent water entering through the openings from contacting a substantial portion of the membrane.
