Fermentation of palm oil mill effluent (POME) produces biohydrogen in a mixture at a specific set condition. This research was conducted to purify the produced mixed biohydrogen via absorption and membrane techniques. Three different solvents, methyl ethanolamine (MEA), ammonia ($NH_3$) and potassium hydroxide (KOH) solutions, were used in absorption technique. The highest $H_2$ purity was found using 1M MEA solution with 5.0 ml/s feed mixed gas flow rate at 60 minutes absorption time. Meanwhile, the purified biohydrogen using a polysulfone membrane had the highest $H_2$ purity at 2~3 bar operating pressure. Upon testing with proton exchange membrane fuel cell (PEMFC), the highest current and power produced at 100% $H_2$ were 1.66 A and 8.1 W, while the lowest were produced at 50/50 vol% $H_2/CO_2$ (0.32 A and 0.49 W). These results proved that both purification techniques have significant potential for $H_2$ purification efficiency.
