听说西国在闹这个系统不知道能否装在我们的潜艇上听说西国在闹这个系统不知道能否装在我们的潜艇上
你是说热核电池？
功率有多少？低于2000KW的直接无视！:o
卫星上用哪个如何

你说的是同位素温差发电，他讲的是质子交换膜PEM，物理和化学的区别哦

A unique numerical method has been developed to model the dynamic processes of bulk evaporation and condensation processes, associated with internal heat generation and natural convection under different gravity levels. The internal energy formulation, for the bulk liquid-vapor phase change problems in an encapsulated container, was employed. The equations, governing the conservation of mass, momentum and energy for both phases involved in phase change, were solved. The thermal performance of a multiphase uranium tetrafluoride fuel element under zero gravity, micro-gravity and normal gravity conditions has been investigated. The modeling yielded results including the evolution of the bulk liquid-vapor phase change process, the evolution of the liquid-vapor interface, the formation and development of the liquid film covering the side wall surface, the temperature distribution and the convection flow field in the fuel element. The strong dependence of the thermal performance of such multiphase nuclear fuel cell on the gravity condition has been revealed. Under all three gravity conditions, 0-g, 10-3-g and 1-g, the liquid film is formed and covers the entire side wall. The liquid film covering the side wall is more isothermalized at the wall surface, which can prevent the side wall from being overheated. As the gravity increases, the liquid film is thinner, the temperature gradient is larger across the liquid film and smaller across the vapor phase. This investigation provides valuable information about the thermal performance of multi-phase nuclear fuel element for the potential space and ground applications.

原来是这个 这个就不清楚了
最有希望上艇的电离堆没没有突破500KW,十年内上不了艇的.

也不一定，我看到1000KW左右就差不多，以柴油主机出内海以后就靠小堆在水下管充电和动力1000KW够用了，关键是小型化的问题。
燃料电池就是燃料电池，核电池就是核电池，不存在什么“核燃料电池”
