NOVELTY - A passive self-breathing direct liquid fuel cell support pole plate comprises window type fuel storage cavity, support pole plate and 3-in-1 membrane electrode, where used liquid fuel is methanol, formic acid or ethanol served as reactant. The support pole plate comprises support plate (1), groove-shaped flow fields and current collecting material. The support pole plate consists of cathode support pole plate and anode support pole plate. The cathode support pole plate and anode support pole plate are same in structure and used in pair.    USE - Passive self-breathing direct liquid fuel cell support pole plate.    ADVANTAGE - The support pole plate has good thermal resistance, insulating performance, water resistance, chemical and aging resistance, and has high mechanical processing performance; and is lighter than stainless steel plate, and has greater supporting intensity than that of graphite plate, thus it is hard to crush. The groove-shaped flow fields are helpful for close contacting membrane electrodes with current collecting material to reduce cell contact resistance, where each single cell can be integrated to a support plate to produce the cell set because support plate is not conductive.    DETAILED DESCRIPTION - The passive self-breathing direct liquid fuel cell support pole plate comprises window type fuel storage cavity, support pole plate and 3-in-1 membrane electrode, where used liquid fuel is methanol, formic acid or ethanol served as reactant. The support pole plate comprises support plate (1), groove-shaped flow fields and current collecting material. The support pole plate consists of cathode support pole plate and anode support pole plate. The cathode support pole plate and anode support pole plate are same in structure and used in pair. The groove-shaped flow fields are parallel flow fields or dot flow fields of determinant arrangement. The groove-shaped flow fields of anode or cathode support pole plate are same or different while assembling passive self-breathing direct liquid fuel cell. The support plate is provided with groove-shaped flow fields which are parallel flow fields in carving way. The parallel flow fields comprises support rib (4) and mass transfer flow fields (5), which are distributed alternately, where current collecting material lead wire port (2) is communicated with the groove-shaped flow fields. The groove depth of each groove-shaped flow field is equal to sum of the thickness of the current collecting material and thickness of the single-side electrode of 3-in-1 membrane electrode. The mesh current collecting material is embedded to the groove-shaped flow fields to obtain the support pole plate of parallel flow fields. The mass transfer channel porosity of the groove-shaped flow fields takes up 40-60% of that of the whole flow fields. The support plate is provided with fixing holes (3), where support pole plate is fixed to cell case by the support plate. The support plate is an unsaturated polyester glass fiber reinforcement plate, its thickness is 1-3 mm. The mesh current collecting material is a plated stainless steel mesh or titanium mesh. The parallel flow fields of groove-shaped flow fields are replaced by dot flow fields of determinant arrangement. The mass transfer channels on dot flow fields of determinant arrangement are circular holes. The area of circular holes takes 40-60% of area of the groove-shaped flow fields. The other parts of support pole plate with dot flow fields of determinant arrangement are same with those of support pole plate with parallel flow fields as the groove-shaped flow fields.
