NOVELTY - An anode flow field board (1) has substrate (11); shunt portion (12) formed by digging a small area of the substrate as a hollow area; and an inlet channel structure connected between the shunt portion and at least one slot body. Each slot body is correspondingly associated with the configured position of the anode for each membrane electrode assembly. An outlet channel structure (15) is connected between the slot bodies and an outlet hole (16). The outlet hole is formed by digging a small area of the substrate as a hollow area.    USE - For fuel cell, such as fuel cell using methanol fuel, fuel cell using liquid fuel, fuel cell using gas fuel, and fuel cell using solid fuel.    ADVANTAGE - The board has an extremely light overall weight and low manufacturing cost; provides the anode fuel and anode product with a fluid field environment for smoothly flowing; has improved current collector function; and achieves uniform density and uniform flow volume after fuel mixing, which could increase the power generation performance of the cell.    DETAILED DESCRIPTION - The substrate is an anti-chemical non-conductor engineering plastic substrate, graphite substrate, metal substrate, plastic carbon substrate, FR4 substrate, FR5 substrate, epoxy resin substrate, glass-fiber substrate, ceramic substrate, polymer plasticized substrate, or composite material substrate. The substrate is configured with a printed circuitry that is electrically connected to current collector sheets (17). The current collector is sheet stainless steel (SUS316) sheet, gold foil, titanium metal, graphite material, carbon metal compound material, metal alloy sheet, or polymer conductive sheet with low resistance. At least one electric component is accommodated in the inner space of the shunt portion. The electric components comprise a temperature sensor, a density sensor, a liquid level sensor, a heating device, a cooling device, or a heating filament.
