Abstract: 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.

Abstract translation: 微电极单元包括衬底和向外延伸以限定阳极和阴极微流体通道的多个间隔开的PEM分配器。 阳极催化剂/电极排列至少一部分阳极微流体通道，阴极催化剂/电极排列至少一部分阴极微流体通道。 在一些实施例中，每个阳极和阴极催化剂/电极可以在PEM分配器的相邻部分的下方延伸。 或者，微细脂肪细胞可以包括多个堆叠的基底，其中第一基底具有第一微流体燃料电池反应物通道。 PEM层可以与第一衬底的第一表面相邻，阳极催化剂/电极层可以邻近PEM层的一侧，阴极催化剂/电极层可以邻近PEM层的相对侧。 粘合剂层可以将第一基底固定到限定至少第二微流体燃料电池反应物通道的相邻基底。
