E=hv and c=frequency x wavelength are equations that only work for massless matter(i.e. electromagnetic radiation/photons). Anything with mass, so electrons, protons, everyday objects, abide by classical mechanics, 1/2mv^2 for kinetic energy, and de broglie's for wavelength.
E=hv is an equation that is measured in Joules per photon, as this equation can be used to find the energy of the incident light, which contains photons. Therefore, when considering these units of Joules per photon, the energy of ejected electrons cannot be found using the equation E=hv, particularly because the units are different if this helps to understand the concept better.
