摘要： In the case in which a fuel cell has a structure in which a cathode (2) and an anode (1) are opposed with the intermediary of an electrolyte layer (3) and the cathode (2) is formed of an electrode to which an oxygen reductase and so on is immobilized and this electrode has pores inside, at least part of the surface of this electrode is rendered water repellent. For example, the surface of the electrode is rendered water repellent by forming a water-repellent agent on the surface of this electrode. Thereby, in the case in which the cathode is formed of an electrode to which an enzyme is immobilized and this electrode has pores inside, a fuel cell that can stably achieve a high current value by optimization of the amount of water contained in the cathode and a manufacturing method thereof are provided.

摘要： To provide a fuel cell that can perform efficient power generation through a simple fuel supply. There is provided a fuel cell that generates electricity through progress of an oxidation-reduction reaction using an enzyme as a catalyst, the fuel cell including at least a fuel-vaporizing layer formed through vaporization of a fuel; an anode to which a vaporized fuel is supplied from the fuel-vaporizing layer; and a cathode connected to the anode in a state in which protons can be conducted. In the fuel cell, since a fuel is supplied to an electrode in a vaporized state, a vaporized fuel is supplied to an inner portion of the electrode and a reaction sufficiently proceeds at the inner surface of the electrode, which can achieve high output due to efficient power generation. Furthermore, even if an enzyme or the like is immobilized on an electrode, the enzyme or the like can be prevented from leaching out into a liquid fuel because a fuel is supplied to the electrode in a vaporized state, which can prevent a decrease in the output caused by leaching out of the enzyme or the like.
摘要翻译：提供能够通过简单的燃料供给来实现高效发电的燃料电池。提供了一种通过使用酶作为催化剂进行氧化还原反应而发电的燃料电池，所述燃料电池至少包括通过燃料蒸发形成的燃料蒸发层; 从燃料汽化层供给汽化燃料的阳极; 以及在可以导电质子的状态下连接到阳极的阴极。在燃料电池中，由于向蒸发状态的电极供给燃料，所以向电极的内部供给汽化燃料，在电极的内表面充分进行反应，由此可以实现高输出高效发电。此外，即使将酶等固定在电极上，也可以防止由于向蒸发状态的电极供给燃料而使酶等浸出到液体燃料中，从而能够防止通过从酶等浸出而产生的输出。

摘要： Provided are an enzyme immobilizing method, a fuel cell and an electrode for the fuel cell which employ the enzyme immobilizing method, and a method for manufacturing the fuel cell and the electrode. The enzyme immobilizing method prevents reduction in enzyme activity when the enzyme is immobilized on the electrode, so as to make it possible to obtain a high catalyst current value. In the method for immobilizing an enzyme on the electrode used in the fuel cell, an enzyme variant with at least one amino acid residue being deleted, substituted, added, or inserted in a wild-type amino acid sequences is used as the enzyme, and the enzyme variant increases in activity through heat treatment. The immobilization is performed within a temperature range which makes it possible to increase the activity of the enzyme variant.

摘要： A needleless injection device has a housing containing a pilot valve connectable to a compressed gas source. A two stage power amplifying valve includes a main valve operatively connected to the pilot valve. The pilot valve and main valve form a two-stage valve with the pilot valve activatable to open the main valve utilizing gas pressure. Compressed gas in a reservoir flows through the open main valve to drive a plunger into an ampule to inject an injectant through a patient's skin. Interlocks are provided to resist inadvertent actuation of the device and a indicator indicates whether there is sufficient gas pressure in the device for another injection.

摘要： The valve control unit of a fuel leakage preventing structure of the present invention includes first and second electrodes. The first electrode is attached to a first member that is movable. When a pressing force is applied to the first member to move, the first and second electrodes are brought into contact with each other, to cause conduction. The first and second electrodes are connected to a control device, and the control device opens a control valve when the first and second electrodes are put into a conducting state. As the control valve is opened and closed by a pressing force in this manner, a fuel solution can be easily supplied.
