A proton has positive charge and an electron (has) a negative charge, but a neutron has neither.
质子带有一个正电荷，电子带有一个负电荷，但这两种电荷中子都没有。
Between these two tiny particles, the proton and the electron, there is a powerful attraction that is always present between negative and positive electric charges.
在质子和电子这两个微粒之间有一个很大的吸引力，而这个吸引力总是存在于正、负电荷之间。
Unlike either the electron which has a negative charge or the proton which has a positive charge, the neutron has no charge at all.
中子既不象带负电荷的电子，也不象带正电荷的质子，它根本就不带任何电荷。
The proton carries a positive charge and the electron carries a negative charge but the neutron carries neither.
质子带正电荷，电子带负电荷，中子两种电荷都不带。
A proton has positive charge and an electron has negative charge.
质子带正电荷，电子带负电荷。
An electron has a negative charge, a proton has a positive charge.
电子带负电荷，质子带正电荷。
Disclosed is a fuel cell having a structure wherein a positive electrode and a negative electrode face each other through a proton conducting material.
本发明提供一种具有正极和负极通过其间的质子导体彼此面对的结构的燃料电池。
