<p><P>PROBLEM TO BE SOLVED: To provide an air cell superior in reliability in which internal resistance is suppressed low, in which workability in filling a negative electrode gel is secured, and in which improvement of pulse characteristics and a maintenance rate in a dry environment is possible. <P>SOLUTION: In the air cell having a positive electrode catalyst sheet to reduce oxygen which turns into the positive electrode active material, and also having a gelatinous negative electrode in which an alkaline electrolytic solution is injected into a mixture of metal powder and a gellating agent which become a negative electrode active material, the thickness of the positive electrode catalyst sheet is 0.15 to 0.25 mm, a Teflon ratio of the catalyst sheet is 20 to 30 wt%, at least 10 wt% or more of 106μm or less particle sizes are included in the negative electrode metal powder, and furthermore, a particle size of an acrylate water-absorbing polymer is made to be 10 to 150μm. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
