摘要:
A microfuel cell includes a substrate and a plurality of spaced-apart PEM dividers extending outwardly to define anodic and cathodic microfluidic channels. An anodic catalyst/electrode lines at least a portion of the anodic microfluidic channels, and a cathodic catalyst/electrode lines at least a portion of the cathodic microfluidic channels. Each anodic and cathodic catalyst/electrode may extend beneath an adjacent portion of a PEM divider in some embodiments. Alternately, the microfuel cell may include a plurality of stacked substrates, in which a first substrate has first microfluidic fuel cell reactant channels. A PEM layer may be adjacent the first surface of the first substrate, an anodic catalyst/electrode layer may be adjacent one side of the PEM layer, and a cathodic catalyst/electrode layer may be adjacent an opposite side of the PEM layer. An adhesive layer may secure the first substrate to an adjacent substrate defining at least a second microfluidic fuel cell reactant channel.
