This paper deals with the fractional Schrödinger-Poisson system
 $\begin{equation*} \left\{ \begin{array}{ll} \varepsilon^{2s}(-\Delta )^su+V(x)u+K(x)\phi u = |u|^{2_{s}^{*}-2}u, & \text{in}\ {\Bbb R}^3,\\ (-\Delta)^{t}\phi = K(x)u^2, & \text{in}\ {\Bbb R}^3, \end{array} \right. \end{equation*}$
where
 $s\in (\frac{3}{4}, 1)$
,
 $t\in(0, 1)$
,
 $\varepsilon$
is a positive parameter,
 $2_{s}^{*} = \frac{6}{3-2s}$
is the critical Sobolev exponent.
 $K(x)\in L^{\frac{6}{2t+4s-3}}({\Bbb R}^3)$
,
 $V(x)\in L^{\frac{3}{2s}}({\Bbb R}^3)$
and
 $V(x)$
is assumed to be zero in some region of
 ${\Bbb R}^3$
, which means that the problem is of the critical frequency case. In virtue of a global compactness result in fractional Sobolev space and Lusternik-Schnirelman theory of critical points, we succeed in proving the multiplicity of bound states.
