摘要:
Disclosed is a preparation method for bio-fuel materials and bio-chemicals comprising the following steps: preparing a medium comprising fermentation waste generated in an alcohol production process; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated. More specifically, the preparation method for bio-fuel materials and bio-chemicals comprises the following steps: fermenting hexoses from a mixture of pentoses and hexoses to produce an ethanol fermentation broth; separating and purifying the ethanol fermentation broth; preparing a medium comprising the fermentation waste produced in the separation and purification step; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated.
摘要:
A fuel processor and a fuel cell system which have a desulfurizer with multiple sensors, and a method of measuring an adsorbent state in of an adsorbent the desulfurizer. The desulfurizer determines the saturation state of the adsorbent using a signal difference between at least two sensors installed adjacent to an inlet and an outlet of the desulfurizer. The desulfurizer provides an accurate determination of the saturation of the adsorbent, and can be used to determine when the adsorbent should be changed. Two desulfurizers can be alternatively used to allow for a consistent fuel flow.

A passive cooling system for a fuel cell stack is provided. The passive cooling system includes a plurality of cooling plates, each installed between every few unit cells, each having flow channels for flowing a primary coolant on at least one surface, and each comprising an inlet hole through which the primary coolant enters and an outlet hole through which the primary coolant that has passed the flow channels leaves; and a heat exchanger installed on a primary coolant flow line connected from the outlet holes to the inlet holes of the cooling plates to change a vapor state primary coolant to a liquid state primary coolant by cooling the primary coolant, wherein a path through which the primary coolant passes is a closed circuit, and the flow of the primary coolant is achieved by natural convection caused by vaporization of the primary coolant.
