Abstract

A passive direct organic fuel cell (10) includes an organic fuel solution and is operative to produce at least 15 mW/CM2 when operating at room temperature. In additional aspects of the invention, fuel cells can include a gas remover (38) configured to promote circulation of an organic fuel solution when gas passes through the solution, a modified carbon cloth (29), one or more sealants, and a replaceable fuel cartridge (350).
