Abstract
A method and apparatus are disclosed for generating electrical power during negative pressure therapy. The apparatus includes a fuel cell, comprising an anode element and a cathode element, arranged to collect biological fluid from a wound site to which a negative pressure is applied and electro-oxidize a component of the biological fluid at the anode element and/or electro-reduce a component of the biological fluid at the cathode element.
