Abstract:
1. A fuel directing reaction device for a passive fuel cell comprising: a substrate, which has a first side and a second side opposite to the first side; a fuel reservoir, which is disposed on the first side of the substrate; a fuel introducing microfluidic channel portion, which is disposed on the first side of the substrate and connected with the fuel reservoir, wherein the fuel introducing microfluidic channel portion can self-propel a fuel from the fuel reservoir by a capillary force; a first rib array portion, which is disposed on the first side of the substrate, and connected with the fuel introducing microfluidic channel portion, wherein the first rib array portion comprises a plurality of first ribs in an interlaced arrangement and each of which has a V-shaped portion with an open side toward the fuel introducing microfluidic channel portion; a second rib array portion, which is disposed on the first side of the substrate, and connected with the first rib array, wherein the second rib array portion comprises a plurality of second ribs in an interlaced arrangement and each has a V-shaped portion with an open side toward the first rib array portion; and a plurality of reaction holes, each of which is disposed on the open side of the V-shaped portion of the second ribs and extends through the substrate to connect the first side and the second side of the substrate.
