Fuel cell stacks and systems with thermal management systems to deliver a liquid heat exchange fluid into thermal communication with the stack and thereafter recycle the stream. In some embodiments, the system is adapted to selectively apportion the recycled liquid stream between a stream that, prior to reuse as a heat exchange stream, is returned to a fluid reservoir and/or selectively cooled, and/or selectively returned to the reservoir and mixed with heat exchange fluid in the reservoir, and a stream that is returned into thermal communication with the stack without returning the stream to the reservoir and/or without heating or cooling and/or without being mixed with additional heat exchange fluid. In some embodiments, the system is adapted to automatically apportion the recycled stream responsive to its temperature. In some embodiments, the system includes a thermostatic valve and/or selectively apportions the recycled stream without requiring an electronic controller or manual input.
摘要:
A fuel cell system according to the present invention has a movement drive device (load) (2), a fuel cell (10) for supplying electric power to the drive device, an electric power storing device (31) consuming electric power equivalent to the consumption power of the drive device, and an electronic control unit (connection control unit) (4) for controlling the connection of the fuel cell to the drive device. Before the fuel cell is connected to the drive device by the control of the electronic control unit, the fuel cell is made to generate electric power equivalent to the consumption power of the drive device, and the generated power is supplied to the electric power storing device. When a fuel cell voltage at the time of supply of the electric power to the electric power storing device is not less than a specified value, the connection between the fuel cell and the drive device is permitted.

A fuel cell power plant is provided for a mobile unit. The mobile unit is provided with a drive device (29) driving the mobile unit when supplied with electrical power. The power plant comprises a fuel cell (21) generating power when supplied with fuel, a battery (27) charged with power generated by the fuel cell, a power regulation device (31) selectively distributing power from the fuel cell (21) and the battery (27) to the drive device (29), and a controller (33) for controlling running operations. The controller (33) estimates the energy required to activate the fuel cell (21), and controls the power regulation device (31) when the energy required to activate the fuel cell is greater than or equal to a determination value so that the fuel cell is not activated and power from the battery (27) is supplied to the drive device (29).
摘要:
A reforming catalyst is composed of a plurality of catalyst layers arranged in series, and when started from a low temperature, preheated air is supplied in parallel to a point upstream of each catalyst layer, thereby the catalyst in each layer is self-heated simultaneously so that the catalyst is heated. After the catalyst is heated, feed of air is temporarily stopped, and supply of fuel gas is started. Next, air is supplied while controlling its flow rate so that temperatures in the catalyst do not exceed the temperature that the catalyst can withstand. Thus, no other special equipment is needed, and the catalyst can be started quickly (cold start). The catalyst can be made compact enough to install it in a electric vehicle.

A control apparatus calculates the capacitor maximum power (PCAPU) that can be supplied to a capacitor depending on the detected value of the temperature of the capacitor, and calculates the output power (PFC) of the fuel cell, the real power of the motor (PMOT) that actually powers the drive motor, and the load power (PAC) that actually powers an electrical load, excluding the drive motor. The control apparatus calculates the motor power limiting value (PMOTU), which is the motor power that corresponds to the capacitor maximum power (PCAPU), based on the output power (PFC) of the fuel cell, the load power (PAC) that powers the electrical load, excluding the drive motor, and the capacitor maximum power (PCAPU). The control apparatus output to the output controller a control command that directs the real power of the motor (PMOT) to take the value of the motor power limiting value (PMOTU) in the case that the real power of the motor (PMOT) is larger than the motor power limiting value (PMOTU). The drivability of a fuel cell vehicle is improved while protecting the capacitor.
