TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: Additionally, preparing method for tubular cathode for direct alcohol fuel battery comprises: (a) preparing monomer solution for gel-casting, taking acrylamide as monomer, taking N,N'-methylene-bisacrylamide as cross linker, and taking tween as dispersant, and taking de-ionized water as dispersive medium, mixing to be monomer solution; (b) adding inter-phase asphaltic coal micro-sphere into the monomer solution (a), mixing evenly each component, obtaining stable sizing agent; (c) adding ammonium sulphate into sizing agent in (b) as initiator, and adding catalyst N,N,N',N'-tetra-methyl-ethylene-diamine at the same time, injecting into die of shaped tubular biscuit, preserving heating after the sizing agent is mixed evenly till the monomer molecule in sizing agent is polymerized to be gel network, obtaining inter-phase asphaltic coal micro-sphere biscuit after de-moulding, drying the biscuit to obtain hard tubular inter-phase asphaltic coal micro-sphere biscuit without crack; (d) sintering the tubular inter-phase asphaltic coal micro-sphere biscuit obtained in (c) in vacuum, obtaining carbon pipe supporter for direct alcohol fuel battery cathode; (e) dipping, lifting and pulling, drying surface of the carbon pipe sintered in (d), preparing respectively diffusion layer and catalyst layer on surface thereof, and coating polymer electrolyte layer on surface of diffusion layer in manner of dropping with dropper, finally obtaining direct alcohol fuel battery cathode after the electrolyte layer is dried and is rolled and solidified on surface of warm table. The process of drying bisque comprises drying the bisque at normal temperature in air whose moisture is more than 85% until volume of the bisque is stable, then drying the bisque at the temperature of 100 degrees C in air. Preferred Composition: The composition in monomer solution comprises (wt.%): monomer (5-15), cross linking agent (0.25-1.5), dispersing agent (0.4-4) and dispersing medium (94.35-79.5). The composition in the slurry comprises (wt.%): middle-phase asphalt carbon microsphere (40-80), monomer solution (20-60), grain size area of the middle-phase asphalt carbon microsphere is 5-30 micrometers, ball milling mode is adopted to mix the slurry for making the slurry even and stable. Preferred Condition: Additionally, the sintering step comprises: first stage: raising the temperature from room temperature to 600 degrees C with the temperature rising speed of 30-60 degrees C/h; the second stage: keeping 600 degrees C for 1-5 hours; the third stage: raising the temperature from 600-1100 degrees C; the fourth stage: keep 1100 degrees C for 1-5 hours; the fifth stage: raise the temperature from 1100-1450-1800 degrees C with the temperature raising speed of 60-120 degrees C/h; the six stage: keep 1450-1800 degrees C for 1-5 hours; the seventh stage: lower the temperature from the highest temperature of 1800 degrees C to the room temperature with the temperature lowering speed is under 120 degrees C/h.
