Abstract : The study demonstrated the feasibility of using microorganisms to produce hydrogen in quantity and purity from natural products for use in simple fuel cell equipment. The study showed Clostridium welchii to be the best organism, and glucose or maltose the best substrate. Optimum conditions for maximum rate of hydrogen evolution both by resting and growing cells in 10-liter containers were evaluated. The maximum rate was 23 liters/hour. Cucumbers and banana proved to be the best natural products. A simple microbial generator using artificial and natural product substrates produced a 3.5-watt output for 24 hours. A periodic pH adjustment was required to maintain this output. Potential field applications for this process are discussed. (Author)
